How Does Water Treatment Work?
We often throw around the word “contamination” and how dangerous it can be in a cleanroom. And if you work in or around cleanrooms, you know how true this is. But to the everyday consumer, products being free from contamination is often taken for granted. We often don’t even think about contamination control! For many, we know that the water coming out of our tap is clean enough to drink and that’s the end of it. But how does that water...READ MORE
Cleanroom Basics: What Is Ultrapure Water?
If you are working with a pharmaceutical or semiconductor manufacturing cleanroom, you most likely have seen ultrapure water in action. This water is used for water for injectables (WFI) in pharmaceuticals and as a chisel for semiconductors. While it has many other purposes, these are the primary two. And those two industries use a lot of ultrapure water! For example, processing a single wafer uses over 1,000 gallons of ultrapure water. For many...READ MORE

What Is 21 CFR 11?
How much time do you spend each day hunting down signatures? Or do you get to use a digital system to endorse documents? If you get to record, verify, and store data digitally, you can thank 21 CFR 11. 21 CFR 11 refers to Code of Federal Regulations Title 21 Part 11: the Food and Drug Administration’s guidance on maintaining data integrity in digital applications. It requires certain attributes from digital systems that are used to gather signatures and...READ MORE
Cleanroom Maintenance Checklist
Cleanroom maintenance is the key to ensuring your cleanroom continues to operate at peak form. Failure to conduct regular maintenance can have devastating consequences for your cleanroom. For instance, in 2018, a NASA cleanroom was contaminated with fungi. While the fungi was found around the cleanroom, it was heavily concentrated around a filter that had been installed 40 years previously and not checked since. As a result, many scientists who had worked in that...READ MORE
3 Automations To Improve Your Cleanroom Workflow
At the end of the day, in a cleanroom: time is money. Cleanrooms are expensive to operate and, while they are running, they have a lot to do. Technicians gown up and put their expertise to work on various applications. But due to the nature of cleanrooms, SOPs and regulations must be minded. So there is constant documentation. This tedious documentation - when done by humans - not only slows down and impedes your workflow, but allows for human error. Thus, it is valuable to...READ MORE
Your Path To A Paperless Cleanroom Part 2
How To Improve Your Cleanroom Data Integrity
What does particulate data collection in your cleanroom look like? Let’s paint a picture together of the current system - or close to it - in the cleanrooms of around 75% of life science companies. A particle counter spits out a printout with dozens of data points on it. A technician tears the printout from the...
Your Path To A Paperless Cleanroom part 1
Did you know 75% of life science companies still use a paper based system in their cleanrooms? That means in an 8 hour shift, you need someone to look at as much as 5,000 individual count data samples which can yield up to 700 print outs. Each of these printouts needs to be reviewed. But before they can be reviewed, there is a whole process they must go through. When the particle counter prints out the information, someone must go retrieve the ticket. They have to rip...READ MORE
Good Automated Manufacturing Practices 5 (GAMP5) And Your Cleanroom

Straining/Sieving This technique is exactly what it sounds like: the filter strains particles out of the air. Similar to the...READ MORE
Your Ultimate Guide To Cleanroom Air Distribution Strategy
We talk a lot about contamination control strategies in a cleanroom, but there is another type of strategy you need to consider: air distribution. This strategy is typically put into place during the planning and building of a cleanroom because it has a lot to do with infrastructure. But understanding your cleanroom’s air distribution strategy will give you a better understanding of your cleanroom’s overall environment. Why Does Air Distribution...READ MORE
Cleanroom Particle Filtration Basics
Your filters are what separates your cleanroom from just some ordinary, run-of-the-mill room. They stop potentially harmful contaminants from entering the room. They prevent yield loss and harm to the end-user. Most importantly, the filters’ MPPS defines your cleanroom’s potential classification. This classification limits your cleanroom’s applications. Cleanroom filtration is defined by the type of filters you use. There are 4 main types of filters you...READ MORE
Photometer vs Particle Counter: Which Is Right For Your Cleanroom?
When you need to classify your cleanroom, do you reach for your trusty photometer or particle counter? Both photometers and particle counters are devices used in cleanrooms to measure particles, but they go about it in different ways and report different data. According to ISO 14644, both are acceptable forms of testing for classification, especially after the 2019 updates. Yet the needs of each cleanroom are unique! But which one proves right for your cleanroom?...READ MORE
Your Basic Guide To Aseptic Filling
Your Basic Guide To Aseptic Filling Did you know that aseptic (or sterile) processing in pharmaceutical manufacturing is relatively new? Sterility requirements were established in the 1920s. Later, during World War II, requirements were created around large scale biological manufacturing of plasma and blood products. Previously, some blood products required post-fill pasteurization, where they underwent the low heat treatment of 60°C for 10 hours. While this does...READ MORE
What Does "As Received Data" Mean During Particle Counter Calibration?
What does a perfect cleanroom look like? Zero contamination, immaculately gowned personnel, and no malfunctioning equipment, ever. That's the dream, right? While perfection might not be attainable, we can work to get as close as possible to it. Not only will operating your cleanroom by these "nearly perfect" standards keep your data in line for easy tracing, but it will also decrease yield loss and increase productivity. So how do we make sure your...READ MORE
Aseptic Environment: Nonviable vs Viable Monitoring
Does it matter what kind of particles exist in your cleanroom? Isn't all contamination bad? On the surface, yes. You just need to know if your cleanroom is contaminated or not. Any contamination poses a risk to the contents of the cleanroom and, in some industries, a threat to the end-user or product. But we need to go a layer deeper: what kind of contamination is present? Not only will this determine the severity and type of threat to your cleanroom and product,...READ MORE
