FILTER INTEGRITY TESTING - FDA Guideline on Sterile

2021-3-19  The bubble point measurement determines the pore size of the filter membrane, i.e., the larger the pore the lower the bubble point pressure. Therefore, filter manufacturers specify the bubble point limits as the minimum allowable bubble point. During an integrity test, the bubble point test has to exceed the set minimum bubble point.

Bubble Point - an overview ScienceDirect Topics

The bubble point test is a method for both characterising a particular membrane and also for testing the integrity of a membrane. The test is based on the fact that for a given fluid and membrane pore size and constant wetting the pressure required to force an air bubble through a pore is inversely proportional to the size of the pore or hole.
