Memtrex-FE-S (MFE-S) validatable sterilizing filter cartridges are designed for sterile filtration of pharmaceutical fluids

MFE validation by Osmonics is based upon the FDA Guidelines that we “establish documented evidence of assurance that a specif- ic process will consistently produce a product meeting its predetermined specification and quality attributes” (FDA 1987). MFE-S is designed for final sterile filtration of phar- maceutical products.

MFE-S is designed for vent and process fluid filtration in val- idated systems where critical fluids need absolute, aseptic and sterile hydrophobic or chemically resistant protection.

A detailed Validation Guide is available from Osmonics to document our rigorous testing for your records and reviews.

The MFE-S filter is just one example of our strong commitment to the pharmaceutical industry. Our complete portfolio includes filters for every stage of pro- cessing, and we offer custom solutions for your unique applications. Osmonics is your complete source for filters, housings and other filtration equipment.
