Web19 dec. 2024 · However the hydrophobic membrane also makes integrity testing in situ difficult (as recommended by ISO 13408-2 First Ed, 2003-03-15, Aseptic Processing of Healthcare Products Part 2, Filtration [2003]) as the membrane must be fully wetted prior to testing by the widely accepted integrity test methods of Bubble Point and Forward Flow. Web11 dec. 2024 · There are 3 major tests used to determine the integrity of a membrane filter: the Bubble Point Test, the Forward Flow Test, and the Pressure Hold Test. All three tests are based on the same physics, the flow of a gas through a liquid-wetted membrane under applied gas pressures. They differ in which part of the flow/pressure spectrum they …
