Integrity Testing of Sterilising–Grade Filters – A Critical Step

Integrity testing of sterilising-grade filters is a critical step in biopharmaceutical manufacturing. Advanced integrity testers enable a number of functions to be used, which make the filter integrity test procedure more efficient, faster and more reliable. Effective measures can be taken that permit integrity test units to be smoothly operated throughout many years. The use of protective filters installed in the test line, as well as of external valves and cleaning functions, provides the highest possible level of safety in integrity testing.
