In accordance with GMP requirements membrane filter cartridges integrity control must be done to ensure the quality of manufactured products. 

Integrity testing of filter cartridges assures the high quality of manufactured products and the absence of membrane defects inside the filter, mechanical damage and system leakages in a whole.

In addition, failure of filter cartridge integrity may occur during operation, i.e. during sterilization process, when the filter is subjected to high temperatures or high pressure, due to hydraulic shock, or because of inadequate sealing when installed in the filter holder. 

According to MU 42-51-19-93 if applied for sterilizing filtration and other critical applications the filter should be integrity tested before and after each filtration process.

Filtration systems can be tested by using automatic instruments only, which ensure clear, unambiguous and reproducible results and prove the quality compliance and filter suitability for the concrete production target.   

"Technofilter" has developed a series of automatic integrity test instruments:
