Description
The Automatic Filter Integrity Testing Machine performs the bubble point test, the most widely used non-destructive integrity test, based on the principle that liquid is retained in filter pores by surface tension and capillary forces, and the minimum pressure required to displace this liquid is directly related to the pore size.
This method:
- Detects minor defects and oversized pores
- Correlates with bacterial retention performance
- Is widely used in product release testing in PET centers
