Memtrex-MP-S (MMP-S) validatable sterilizing grade filter cartridges are designed for final sterile filtration of pharmaceutical products. Our modified polyethersulfone (PES) membrane’s asymmetric pore structure combined with extremely low protein- binding characteristics provides high throughputs.

MMP-S is the sterilization (S) Grade MMP for validation uses. This commitment by Suez Water Technologies to validation is based upon the FDA Guidelines that we “establish documented evidence of assurance that a specific process will consistently produce a product meeting its predetermined specification and quality attributes” (FDA, 1987). MMP-S is designed for final sterile filtration of pharmaceutical products. The double-layer PES membranes provide low protein-binding, high throughput and are 100% integrity tested.

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

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