Comments Off on Selecting the Right Ultrasonic Cleaning Detergent for Regulated Industries
Regulated industries use ultrasonic cleaning for pharmaceutical equipment, medical devices, surgical equipment, labware, optical instruments, and dental equipment because it is highly effective at removing soil and debris before sterilization, especially on intricate or hard-to-reach parts. A detergent must be used in conjunction with ultrasonic cleaning in order to effectively remove most soils. A multipurpose cleaner is ideal because of its versatility.
3 Things to Consider When Selecting the Right Detergent for Your Ultrasonic Cleaner
1. What are the Soils?
Understanding which soils you need to remove will guide you in choosing the right detergent. Micro-90® is an alkaline cleaner that is designed to work well on a broad spectrum of soils. It is extremely effective for removing oil, grease, wax, tar, flux, particulates, and biological debris.
Most commercial critical cleaners are effective in removing dirt, but many are also corrosive, harmful if inhaled, and environmentally hazardous. Safer cleaning detergents will be free of phosphates, solvents, silicates, phenols, and substances of very high concern.
View this video to see the effectiveness of Micro-90 in ultrasonic cleaning.
Using Micro-90 in Ultrasonic Cleaning
Micro-90 is a multipurpose, alkaline concentrate that provides superior performance in ultrasonic cleaning. The ingredients in Micro-90 penetrate tough oils and greasy films, allowing the soil to become suspended in the solution without the risk of redepositing. These properties make Micro-90 just as effective as corrosive cleaners without the health or environmental risks. Micro-90 does not contain solvents, phosphates, or heavy metals. In fact, Micro-90 removes hard metals in water that would otherwise detract from the detergency of the solution.
The ingredients in Micro-90 were chosen for easy validation in an FDA process. Reports can be provided upon request. It is also NSF registered as a USDA-A1 Cleaner. Micro-90 can be used in concentrations as low as 0.5% up to 5%, and concentration can be easily determined by conductivity. Micro-90 has a high cloud point, making it easy to see when parts are clean. When properly rinsed, Micro-90 leaves no residue.

What is Cleaning Validation?
Cleaning validation is used to ensure that a cleaning procedure removes all trace soils, cutting fluids, fingerprints, particulates and cleaning agents from surfaces in regulated processes. Any residue must be removed to a predetermined level of cleanliness. Cleaning validation processes protect against the cross-contamination of ingredients from one batch to another, ensure that surfaces or devices are free of residue prior to any further sterilization process, and assist in ensuring product quality.
Cleaning validation is required for use in industries following Good Manufacturing Practices (GMP) as outlined by the US FDA. Manufacturers in the pharmaceutical, medical device and food and beverage industries all use cleaning validation methods to ensure that their equipment is free of waste and that subsequent products manufactured on that equipment are not jeopardized by any remaining soils or soap residue.
FDA guidelines for cleaning validation require specific written procedures detailing how cleaning processes will be validated. These should include:
Who is responsible for performing and approving the validation
Acceptance criteria
When revalidation is required
Sampling procedures
Analytical methods to be used
Documentation of the studies and results
A final conclusive report stating that all residues have been removed to the predetermined level
If any part of the cleaning process is changed, the cleaning validation process must also be updated.
Cleaning Validation Methods
Various analytical methods can be used to detect cleaner residues on equipment. Each method is unique to the specific cleaner used. Cleaner manufacturers should be able to provide detailed validation methods for their products.
Regulated industries rely, in most cases, on quantitative validation methods. Quantitative validation methods provide measurable and exact results, whereas qualitative validation methods involve more subjective methods, such as visual observations.
HPLC (High Performance Liquid Chromatography)
HPLC stands for high performance liquid chromatography. HPLC validation methods can pinpoint exact ingredients. This validation method uses pressure to force a solution through columns to separate, identify and quantify each of its components.
The columns are filled with a solid adsorbent substance. As the solution is forced through the column, each of its components reacts differently to this substance. This results in varying flow rates for each component in the solution. The sample solution is separated into its individual elements by the rate at which they flow out of the column.
Once the individual components of the sample solution are separated, various types of detectors can be used for identification. Some common detectors include:
CAD – charged aerosol detector
DAD – diode array detector
MS – mass spectrometry
HPLC validation methods separate liquids into their individual components. This information is then used to determine the level of residue of an individual component so that predetermined acceptable levels of cleanliness are met. HPLC is the most common type of quantitative cleaning validation method currently used.
TOC (Total Organic Carbon)
TOC stands for total organic compound. TOC validation methods detect carbon content in a tested sample. The results are not ingredient specific. The amount of carbon in the sample can come from any one of a number of varying sources including contamination, a dirty tank, testing equipment, ingredient residue or cleaner residue. The objective is that the overall results of TOC testing meet the predetermined acceptable levels. Results that exceed the predetermined levels are not acceptable.
UV VIS
UV VIS stands for ultraviolet visible spectroscopy. This detection method relies upon the absorption of light to quantitate chemicals at specific wavelengths. Sometimes, a chemical agent is added to the rinse water sample to make key ingredients visible. Chemicals absorb light differently at different wavelengths.
Methylene blue, for example, is routinely used to react to sulfonate surfactants and detect detergent residue. The intensity of the color is an indication of how much sulfonate remains in the sample.
In the illustration above, the fluid at the top of the tubes shows the water in the solution. The fluid on the bottom indicates the amount of chloroform in the test sample. As the concentration of Micro-90 increases, more sulfonate is being pulled out of the top water level by methylene blue and the methylene blue-sulfonate complex enters the bottom chloroform layer resulting in an increasing blue intensity.
UV VIS is an older technology and is not as used as often as HPLC.
The Role Of The Cleaner Manufacturer
Cleaning validation is a critical part of the manufacturing process in regulated industries. Validation methods must be developed, planned and included in the production method. Since cleaning validation methods are unique to the cleaner used, it makes sense to expect the manufacturer to provide support. By relying on the cleaner manufacturer for detailed validation methods, manufacturers in regulated industries can focus their resources on manufacturing and product development, saving a great deal of time and money.
Comments Off on Guidelines For Cleaning Pharmaceutical Processing Equipment
Cleaning pharmaceutical processing equipment is challenging. Cleaning methods, soils present, type of manufacturing equipment, surfaces cleaned, choice of cleaning detergent and temperature should all be considered when setting up a cleaning procedure. Cleaning validation methods are required. The entire cleaning process must be standardized and documented according to the FDA’s cGMP regulations.
Why Clean Pharmaceutical Processing Equipment?
Maintain product quality.
Remove all trace ingredients to prevent the transfer of ingredients from one product to the next. This is especially important when multiple products are produced on the same equipment.
Prevent equipment malfunctions that may lead to product contamination.
Provide a clean surface for disinfection. Surfaces cannot be properly sanitized or disinfected if they are not thoroughly cleaned first.
Comply with local and international standards and regulations to ensure consumer safety and avoid legal issues.
Increase plant performance and productivity by diminishing waste, maintaining equipment and preserving product quality.
Enhance worker safety by providing a clean working environment and smoothly functioning equipment.
Establishing A Cleaning Procedure
Federal Regulations
Pharmaceutical manufacturers are required to set up a fully documented written cleaning procedure for each piece of processing equipment in compliance with FDA 21 CFR Part 211.67. Documentation should include:
Responsibility for equipment cleaning and maintenance
Cleaning and sanitization schedules
A detailed description of the cleaning procedure
Removal of previous batch identification
Protection of clean equipment
Inspection of equipment prior to use
Manufacturers must outline each of these steps in detail to be sure that all processes are followed clearly and succinctly.
Cleaning Procedures
Federal regulations require a very specific description of each step of the cleaning procedure. The following details should be documented.
Frequency of cleaning – including time requirements between processing products and cleaning
Cleaning tools used – any sponges, brushes, scrapers, sprayers, wipes or equipment used to aid the cleaning process
Establishment and sequence of each cleaning step
Identification of each specific piece of equipment to be cleaned, including instructions for cleaning between batches of the same or different products
Cleaning method – clean-in-place (CIP) or clean-out-of-place (COP)
Detailed instructions for any required disassembly and re-assembly of equipment if COP methods are used. Instructions should specify the parts to be removed and any assembly aids used during this process.
Identification of all cleaning detergents and detailed instructions for their use. Usage instructions should include amounts, concentration, temperature, dwell time and application method.
Soils found on pharmaceutical processing equipment may be traces of the various ingredients used in production or soils from the actual manufacturing process such as oil, grease, dust or minerals. Understanding the soils that are present will guide your choice of cleaning detergent.
Gels, polyethylene glycol, oils, titanium dioxide, dyes, silicons, flavorings, petrolatum, paraffin, proteins, steroids, sugars, alcohol, stearates, and cornstarch are some of the typical foulants that are often found on pharmaceutical processing equipment.
Each type of soil is unique and requires the proper detergent to thoroughly clean the surface. Choose a cleaner that will best attack the soils you are trying to remove. Alkaline cleaners are the best choice for cleaning soils such as gels, dyes and petrolatum, while citric acid based cleaners are better suited for removing titanium dioxide. Protein or starch-based soils may require the use of an enzyme cleaner. Use the table below to help match the most effective type of cleaner to each kind of soil.
Type of Equipment
Mixing tanks, tablet presses, capsule fillers, centrifuges, granulators, filling lines, mixers, conveyors, filters, fluid lines, batch process tanks, tubes and flasks all need to be thoroughly cleaned. The design of the equipment must be taken into consideration. By nature of its construction, some types of equipment will be more difficult to clean than others. Hidden parts and blind holes present unique challenges.
Another important factor to consider is the how the equipment is used. Are you cleaning a dedicated production system or equipment that is used to produce a range of products? Processing equipment used to produce multiple products has a greater chance of cross contamination of ingredients.
It’s also important to select a cleaner that is compatible with the surface of the equipment you are cleaning. The cleaner manufacturer should be able to guide you and provide compatibility studies for their products.
Cleaning Method and Location
Clean-in-place (CIP) or Clean-out-of-place (COP)?
CIP is generally used for large systems and components that cannot easily be taken apart. CIP often results in less downtime since it eliminates the need to take apart or move the equipment. Automated systems, spray systems and immersion are all examples of CIP operations.
COP is most often used for smaller pieces of equipment or smaller parts of larger equipment that can be removed and re-assembled after cleaning. COP can involve either manual washing or use of machine washers. Specific instructions for disassembling and re-assembling equipment must be followed.
What cleaning method will you use?
Manual, ultrasonic, spray, machine and automated systems are all used for cleaning pharmaceutical equipment. The type of cleaning method used will impact your choice of detergent. Automatic parts cleaners and high-pressure washers require low foaming detergents.
Temperature
In most cases, increasing the temperature is one of the best ways to speed up or improve the cleaning action. The temperature parameters that should be used for any individual cleaning application will depend upon the equipment and the soils that are present, as well as your choice of detergent and wash method. Check with the manufacturer for the maximum suggested operating temperature for your detergent.
Dwell Time
The length of the cleaning cycle contributes to the effectiveness of your cleaning application. In most cases, a longer dwell time will improve the results. However, all factors – soils, temperature, substrate, detergent and cleaning method must be taken into consideration.
Rinse Step
Thorough rinsing should follow cleaning. Rinsing removes any excess detergent left on the item. For critical cleaning applications, it is best to use deionized or distilled water, as rinsing with ordinary water may introduce new contaminants.
Cleaning Validation
Cleaning validation is a part of the regulatory compliance process for cleaning pharmaceutical processing equipment. Validation ensures that all equipment is washed according to previously determined standards and that all traces of soil and detergent are removed. Validation methods are unique to each detergent and should be available from most cleaner manufacturers.

Comments Off on Save Time And Money With Preventative Maintenance
It’s summer! It’s time to relax and enjoy the warmer weather. Kids are out of school, daylight hours are long, families flock to beaches and it seems like just about everyone takes a vacation.
While summer means various things to different people, for many manufacturers summer means factory shutdowns, plant retooling and scheduled maintenance operations.
What is Preventative Maintenance?
We’ve all been there. Any of these scenarios ring a bell? A long road trip and your car won’t start. You’re hosting Thanksgiving dinner and your oven isn’t working. Or, it’s the worst heat wave of the summer and your air conditioning unit dies. Regardless of the scenario, we can all agree that malfunctioning equipment is extremely aggravating. If only there were a way to prevent these things from happening!
While we can’t prevent all unplanned breakdowns, there are actions we can take to minimize their occurrence. That’s where preventative maintenance steps in. Preventative maintenance refers to regularly scheduled maintenance operations designed to keep equipment functioning optimally throughout the year to help prevent unplanned breakdowns.
Similarly to taking your car to the shop for regular oil changes or servicing your air conditioning unit annually prior to the summer heat, manufacturing plants can take steps to regularly inspect and service their equipment to help prevent costly and untimely breakdowns.
Why Should You Perform Preventative Maintenance?
Simply put, preventative maintenance saves you time and money. Equipment breakdowns are costly and inconvenient. Depending on its function, one piece of malfunctioning equipment can bring an entire plant to a grinding halt leading to lost production and expensive repairs.
Isn’t taking a piece of equipment out of commission to perform preventative maintenance equally as time consuming and expensive? Absolutely not! Sure, maintenance tasks take time and cost money, but planning for them minimizes the bite.
Would you prefer to take your equipment out of commission during a slow period or on your busiest day of the year? Imagine the oven at your local pizzeria breaking down on Super Bowl Sunday. There’s no way to recoup those lost sales!
Parts and labor almost always cost less when it isn’t an emergency repair situation. Having spare parts shipped overnight is not cheap! And, finding service personnel who can drop everything and come right away isn’t always a reality.
Many manufacturing plants shut down for a short time during the summer for retooling in preparation for new production runs. Planning preventative maintenance to coincide with scheduled plant shut downs is a win-win.
7 Benefits of Preventative Maintenance
Increase equipment life
Improve functionality and reliability of equipment
Decrease unplanned breakdowns
Less costly repairs
More productive operations
Maintain product quality
Reduce risk of worker injury
The expression “the best offense is a good defense” perfectly sums up the principle of preventative maintenance. Advance planning keeps costs down and helps keep your equipment running smoothly and efficiently.
Setting Up A Preventative Maintenance Plan
Obviously, every manufacturing plant is unique and each one may have distinct maintenance needs. But, universal considerations that come into play when setting up a preventative maintenance plan include frequency, responsibility, identification of specific tasks and monitoring of the process.
Frequency
How often should equipment be inspected and repaired? This will depend upon your industry and the type of equipment. Scheduled maintenance is often based upon time intervals, equipment usage, or specific trigger events.
Time triggers are based upon specific calendar intervals. Do you inspect and service the pumps in your plant every three months? Or, do you check the antifreeze in your vehicle prior to the onset of cold weather? Similar to your annual physical with your physician, time triggers are maintenance activities based upon the passage of specific periods of time.
Usage triggers are based upon how and when the equipment is used. Examples of usage triggers are changing the oil in your car every 5,000 – 10, 000 miles, or cleaning the processing lines and tanks in your manufacturing plant after each production run.
Event triggers are marked by equipment performance. In wastewater treatment facilities, filter membranes are often cleaned when their flux rate drops by 10 percent. Other examples of event triggers are sharpening a knife when it becomes dull or filling your car tires with air when the pressure drops below a specified level.
Responsibility
Who is responsible for performing scheduled maintenance services? Are the drivers and technicians that use the equipment expected to perform preventative maintenance activities? Or does your facility have a specified maintenance team that inspects and repairs equipment on a regular basis? It’s important for the entire team to know who to go to for regular upkeep of their equipment.
Identify specific maintenance tasks
What maintenance operations should be conducted on a regular basis? Not only will this vary based upon your equipment and your industry, but it may also differ from one plant to another. A checklist of each and every preventative maintenance task should be developed and followed. Common maintenance tasks may include inspecting and testing functionality, cleaning equipment and replacing parts.
Maintain records
All maintenance activities should be recorded and tracked. This helps in planning future maintenance schedules, estimating and keeping track of costs, and monitoring equipment safety and functionality. Most companies use software designed for this purpose, but manual records can also be used.
Plan Ahead
When things are running smoothly it’s easy to overlook common maintenance chores and rationalize that it’s not worth the time to regularly inspect and repair parts. But nothing could be further from the truth. Proper maintenance helps ensure that your equipment is working correctly and your facility is functioning efficiently. Investing the time and money to set up and follow a regular maintenance plan will provide long-term savings by keeping your business functioning smoothly and efficiently.

Comments Off on How do I Choose the Best Detergent for My Cleaning Application?
It’s easy to see that you have a dirty surface that needs to be cleaned. Figuring out what type of cleaner to use can be tricky! Choosing the right product from the outset will make your cleaning task easier, quicker and more efficient. So, how do you know which detergent to use?
Dirt is Dirt, Right?
Absolutely not! All soils are different and need to be treated properly. A detergent that works well for cleaning grease and oil might not be the best choice for getting rid of soap scum or starchy soils. While some cleaners may work well for a broad spectrum of soils, others may be needed to target specific types of dirt.
Alkaline cleaners work well for organic soils like oils and grease, while acid based cleaners are more effective on inorganic soils such metals and salts. Knowing what type of soil you are dealing with is an important step to choosing the right detergent.
This helpful chart matches detergents to soils commonly found on parts and equipment in laboratories, pharmaceutical plants, food & beverage manufacturing sites, medical devices, filter membranes and manufacturing facilities.
What are You Cleaning?
Glass? Metal? Rubber? Electronic parts? Filter membranes? Understanding how different detergents affect different surfaces will certainly have an impact on your choice of cleaner. It’s important to be sure that the detergent you are using is compatible with the surface you are cleaning.
The manufacturer of the cleaner should be able to provide you with compatibility information for the product you are using.
How are You Cleaning?
The cleaning method you plan to use also plays a role in choosing a detergent. Some of the more common methods used in manufacturing and laboratory applications include:
• Ultrasonic cleaning
• CIP (clean-in place)
• Manual or hand wash
• Automatic washers
It’s important to choose a detergent that works well for your chosen cleaning method. For example, if you are using an automatic washer it’s wise to use a low foaming cleaner. Otherwise you may end up with a room full of foamy suds. While this is great fodder for TV sitcoms, it’s not so funny in real life.
Is Your Cleaner Safe?
There are many cleaners on the market that do a great job at removing dirt, but they contain solvents and other harmful ingredients. Look for cleaners that are both effective and safe. Many cleaners are biodegradable. Try to avoid products that contain phosphates, solvents, silicates, phenols, and substances of very high concern.
International Products Corporation’s (IPC) cleaners are safe for personnel, materials, equipment and the environment. Yet, they are powerful enough to remove the most difficult soils. This makes them excellent alternatives to hazardous solvents and chemicals frequently used for precision cleaning applications.
The Manufacturer Matters
When you select a product for your critical cleaning application you should be equally as concerned with the support provided by the manufacturer as you are with the product performance.The benefits of working with an experienced specialty cleaner manufacturer are that they can offer technical guidance and provide a variety of products to best meet your needs. Cleaner manufacturers should be able to assist their customers by providing validation methods, compatibility studies, toxicology reports, regulatory compliance, free product samples, and technical support.
There are so many variables that exist in choosing the right cleaning product. Remember to consider the soils, the surfaces, the cleaning method, the safety and the manufacturer. With careful thought and planning you can find a cleaner that meets all of your specifications. Choosing wisely makes a difference!

5 Ways To Know When To Change Your Cleaning Solution
Choosing the best cleaner for your critical cleaning application takes time and careful consideration. With so many choices out there it can be difficult to figure out which cleaner is the best choice for your specific needs. Factors to consider:
• What is the surface being cleaned?
• What are the soils?
• What’s your cleaning method? Manual? CIP? Machine? Ultrasonic?
• What is the cleaning temperature?
• Do you need a validation method?
You’ve done your homework, run trials and have chosen the right cleaner for your cleaning application. Now it’s time to start to clean!
How much cleaner should I use?
Determining how much cleaner to use will vary based on the parameters of your unique cleaning application. International Products Corporation (IPC) recommends using a 1% – 2% concentration of their specialty cleaners for most applications. Pouring the water into the tank first, and then adding the detergent, helps to avoid excess foaming when preparing your cleaning solution. The chart below is helpful:
How do I know when it’s time to change the solution?
For many industrial and critical cleaning applications, it is extremely important to use a consistent cleaning process and keep the cleaning solution at a desired strength. Concentration control methods are procedures used to determine the concentration of a cleaning solution to ensure process consistency. When the concentration of the detergent drops, you know it’s time to change it.
IPC recommends five methods for testing the cleaning solution to determine the cleaner concentration:
1. Refractive index
2. Conductivity
3. Total alkalinity
4. Total acidity
5. Foam height
Refractive Index
Refractive index is the “measure of the bending of a ray of light when passing from one medium into another.”¹ A refractometer is used to measure refraction. The refractive index is one way of measuring the amount of a substance in an aqueous solution. A higher refractive index indicates a higher amount of cleaner present in the solution. Conversely, a lower refractive index indicates a lower concentration of cleaner in the solution. If changes to the refractive index are found, it’s time to change your cleaning solution.
Conductivity
Conductivity “measures the ability of a given substance to conduct an electric current.”² Conductivity, measured in micro-siemens, can be used to determine the concentration of a cleaning solution. Cleaning solutions have a higher conductivity than water. So, a drop in the level of micro-siemens in your solution is an indication that it’s time to replace it.
Total Alkalinity
This method is used for cleaners that are alkaline based (a pH above 7). Total alkalinity measures the ability of a cleaner to neutralize acid. It assesses the cleaning solution’s buffering capacity – its resistance to changes in pH caused by acid. Total alkalinity is tested by performing a titration, a technique where a solution of known concentration is used to determine the unknown concentration of another solution.
Alkaline builders bind hard water ions, so the surfactants can do their job. Without sufficient alkaline builders, the surfactants would come out of solution and become ineffective.
If the results show that the pH of your solution has decreased by one full pH unit, it’s a good indication that it’s time to change your cleaning solution.
Total Acidity
This method is used for cleaners that are acid based (a pH below 7). Total acidity measures the ability of a cleaner to neutralize alkalinity. Similar to total alkalinity, total acidity is also tested by performing a titration. Changes in the pH of your cleaning solution occur once the soil load capacity of the cleaner has been saturated, indicating it’s time to change the solution.
Foam Height
Surfactants in cleaning solutions reduce surface tension, and, as a result, air may become entrapped. This leads to the formation of small bubbles or foam. If the cleaning solution is agitated, either by shaking vigorously by hand or in a blender, a layer of foam will form. The total volume can be measured in a graduated cylinder, and a foam level curve can be created by plotting the known concentration of the detergent versus the measured total volume. If the foam heights of various known concentrations of detergent are calculated, an equation can be created to determine the concentration of future cleaning solutions whose concentration level is unknown.
All of these methods for calculating the concentration of detergent in a cleaning solution can be converted into simple equations. The data obtained can be plotted on a graph and the slope of the line can be used to calculate the concentration of detergent in your cleaning solution. If you see that the amount of detergent has dropped, you know it’s time to change your cleaning solution.

Tablet presses that are not well maintained can cause a multitude of problems, creating defective products that are mal-formed, contaminated or contain improper dosages. One of the most important steps to maintaining your tablet press is keeping it clean. It’s also important to have systems in place to validate and document the cleanliness of the equipment.
10 Key Steps For Cleaning Tablet Presses:
1.Clean the Exterior: Wipe away all visible dirt on the exterior of the press and vacuum off any excess formulation. Do not use compressed air to blow off excess powders. Compressed air can trap powders in hidden housings, crevices and pockets causing problems down the line. 2.Visual Inspection: Examine the press to assess the condition of the parts. Look for signs of wear or damage on tablet punches and punch heads, and earmark any parts that need repair or replacement. 3.Prepare the Press for Cleaning: Carefully dismantle removable machine parts for thorough cleaning. Tooling, punch heads, feed frames, guards and plates can often be removed for cleaning purposes. 4.Use the Proper Equipment: Stiff nylon punch guide brushes and die seat cleaning tools help to access hidden areas of the press that might contain traces of debris. It’s important not to use any unnecessary force, since tablet presses are delicate and can be easily damaged if not carefully handled. 5.Choose the Right Cleaner: Your choice of cleaner will depend largely upon the soils that are on your press. Are you removing Oils? Gels? Starches? Enzymes? Use this chart to help match a cleaner to the soil. You’ll also want to consider the surface you are cleaning to be sure you are choosing a compatible cleaner.
6. Set Up a Proper Cleaning Method: In addition to using the right cleaning product, it’s also important to consider other variables to establish your cleaning protocol. All of the following should be considered:
a. Amount of Detergent
b. Temperature
c. Dwell time
d. Cleaning method
e. Type of water
7. Rinse: Thorough rinsing should follow the cleaning. Rinsing removes any excess detergent left on the item. For critical cleaning applications it is best to use deionized or distilled water, as rinsing with ordinary water may introduce new contaminates. 8. Validation: Cleaning validation helps identify if there is any remaining residue from soils and cleaners, and helps prevent contamination. Quantitative validation methods, available from most manufacturers, should be used for critical cleaning applications. 9. Disinfect: If required, disinfection should be done after the press is cleaned and soils are removed. 10. Dry Parts Thoroughly: Parts should be completely dried to prevent rusting, corrosion or discoloration.
Setting up an established cleaning routine for your tablet press will help keep it running smoothly and efficiently, and may even extend the serviceable life of your equipment. Regular cleaning will also help prevent regulatory issues and product problems. A few small steps spent on regular cleaning can be a giant leap toward savings and efficiency in the long run.

Comments Off on 5 Ways to Keep Your Lab Equipment In Tip-Top Shape for 2018
It’s January, the start of a new year and a time when people traditionally promise to make positive changes. Maybe it’s a commitment to exercising or healthy eating, a vow to save money, or maybe even a pledge to stop smoking. Whatever your resolution might be, most of us are in agreement that this is an excellent time of year to start fresh and engage in new behaviors.
So why not also set a New Year’s resolution for your professional life. The flip of the calendar is an excellent time to establish a regular maintenance plan for your laboratory equipment.
Just like a car, laboratory equipment must be properly maintained and kept in good working order. Car ownership comes with responsibilities like changing the oil, topping off fluids, rotating tires and washing the vehicle. Performing these actions regularly helps keep your automobile running smoothly, avoiding breakdowns. While no one likes the inconvenience of taking their car in for service, it’s much better than having to call and wait for emergency roadside assistance.
Likewise, proper maintenance of lab apparatus helps to ensure that your equipment is working correctly and your lab is functioning efficiently. Analyzers, centrifuges and microscopes have to provide accurate readings, and pipettes, beakers, slides and flasks need to be kept clean. Failure to properly maintain lab equipment can have a direct impact on test results.
5 Steps for Maintaining Lab Equipment:
1. Inspection
Inspect equipment on a regular basis. Examining equipment regularly helps discover any irregularities and ensures repairs are made on a timely basis, preventing damages from getting worse. Malfunctioning lab equipment should be repaired at once. 2. Repair/Refurbish
Refurbished equipment is completely disassembled and thoroughly cleaned. Some parts are polished and some may need lubrication. Faulty parts can be replaced. The reassembled apparatus frequently works just as well as a brand new piece of equipment. 3. Calibration
Keeping your equipment properly calibrated helps increase its accuracy to ensure that data is not corrupted. Inaccurate calibration can result in skewed data. 4. Clean, Clean, Clean
Regular cleaning is one of the easiest ways to keep your equipment functioning properly. Apparatus that is not thoroughly cleaned can yield inconsistent results. The exterior surfaces of all equipment should be wiped down on a daily basis, after each use. A complete cleaning should be performed at least once a week. Be sure to take these factors into consideration:
• Set up a proper cleaning protocol
• Use the right detergent for each job (this will depend upon the soil and the type of equipment)
• Rinse thoroughly after cleaning
• Avoid cross contamination
• Clean equipment thoroughly prior to disinfecting
• Validate your cleaning process if required
5. Maintain Safety Standards
A well-organized lab will run more efficiently. Supplies and chemicals should be clearly labeled and stored. Safety equipment, such as fire extinguishers, showers, first aid kits, and eye wash should be present and well maintained. Lab personnel should be sure to wear protective gear such as gloves, goggles, lab coats and masks. Chemicals should be disposed of properly as instructed on the SDS.
Properly maintained lab equipment is essential for accuracy and consistency of test results. Investing the time and money to set up and follow a regular maintenance plan will provide long-term savings by keeping your laboratory functioning smoothly and efficiently. This is one New Year’s resolution you’ll certainly want to keep!

Removing stubborn soils can be challenging. Oil, grease, gels, wax, dyes, flux, emulsifiers and biological debris are just some of the soils that are difficult to get rid of. It can be a daunting task to find a cleaner powerful enough to remove these soils, and is also non-hazardous and environmentally friendly.
Enter Micro-90® Micro-90 is a mild, yet powerful, multi-purpose, formulated cleaner that is effective in both industrial and critical cleaning applications. This unique detergent contains chelants and anionic and nonionic ingredients which combine to produce a variety of cleaning actions.
