Pharmaceutical QA

Our Technical Service Team performs application testing for customers all the time. While many of the tests are routine analyses of the particle content or evaluations of a clogged filters, there are other tests, too. Those include chemical compatibility tests and tests in support of validation of a filter for use in a pharmaceutical operation.

One set of filter qualification/validation tests was done for an animal serum processor that was experiencing serious operational issues. 

As with all of our Success Stories, we have removed any identifying information about the company or details about the final product. We focus on how our Technical Service Team addressed a filtration challenge through analysis and testing. Specific challenges have at least some similarity to many others, so learning about how one situation is resolved may lead to ideas on approaching other challenges.

The new Success Story you can access is "Success – Sterilizing Filtration of Animal Serum"


An animal serum processing company wished to evaluate Critical Process Filtration capsule filters to replace those of an exxisting supplier.

  • The customer was redesigning their filtration process (with the help of our Technical Service Team) to address premature filter plugging leading to multiple mid-batch filter changes and resulting product loss
  • Issues with the prefiltration process had been addressed by our team (see separate Success Sotry)
  • Customer wished to purchase all filters for this process from a single supplier and requested qualification/validation testing

Follow the link to learn more about how we solved this and other challenges.
