Pharmaceutical & Biopharmaceutical Filter Products

There are many critical filtration applications in pharmaceutical and biopharmaceutical production. A wide range of filtration devices with multiple media options and micron ratings are needed to cost-effectively perform the many filtration tasks that produce a safe and effective product.

Media

Our polyethersulfone (PES), nylon, hydrophilic polyvinylidene fluoride (PVDF), hydrophobic polyvinylidene fluoride (PVDF), blended cellulose and PTFE membranes, pleated and melt-blown polypropylene depth media, and pleated fiberglass media are available in multiple filter formats for scale-up. Disc filters for laboratory research support the development of new products and processes. Small capsule filters are available for bench scale testing of process variables, and our large disposable capsule filters, cartridge filters and cartridge filter housings allow scale up to pilot and full production, all with the same membrane or media.

Services

Critical Process Filtration partners with users to develop cost-effective filtration systems and perform application-specific tests for filter performance and safety. All of our pharmaceutical and biopharmaceutical grade products are supported by multiple Services available to help you validate your filter performance.
