Life Sciences Radiation Safety Filter Integrity Tester The LabLogic Bubble Point Filter Integrity Tester is a simple to use and compact system which is compatible with most commonly used filters.

Ensuring the integrity of sterilising filters The integrity testing of sterilising filters is a fundamental requirement of critical process filtration applications in the pharmaceutical and PET industries. The ultimate measure of a sterilising filter's performance is bacterial retention. The most widely used non-destructive integrity test is the bubble point test. The bubble point test exploits the fact that liquid is held in the pores of a filter by surface tension and capillary forces. The minimum pressure required to force liquid out of the pores is a measure of the pore diameter. The bubble point...
