Integrity Testing of Sterilising–Grade Filters

Fig. 1: The use of a hydrophobic protective filter in the test line doesn’t have an impact on the test result. This example shows a bubble point test on a 0.2 µm Sartopore 2 filter. The bubble point curve without a protective filter is almost congruent to the one with a protective filter. Both tests showed identical results.
