Various regulatory guidelines require integrity testing of sterilizing filters used in the processing of sterile solutions, such as large volume parenterals (LVPs) and small volume parenterals (SVPs). With many biopharmaceutical manufacturers now testing filters before and after use, there is a need for non-destructive test methods that are fast, reliable, and repeatable. The Intelligent Integrity Tester Certitest® 20 meets this need by enabling non-destructive integrity testing to be performed inline or offline on filtration devices.
