Features and Benefits

PES Asymmetric PPS is a family of pharmaceutical grade, Polyethersulfone (PES) sterilizing filters. This double layered, hydrophilic filter is optimized for retention and provides added security when compared to a single layer model.

Delivers high flow and throughput across a wide pH range
Low binding characteristics (much lower than cellulose acetate and nylon) for filtering liquids with preservatives and proteins that can adsorb to media
Pore sizes: 0.03 - 1.2 microns

Quality Assurance

PPS filters are 100% integrity tested. CPF filters are developed and manufactured under an ISO 9001:2015 certified Quality Management System and designed to be used in cGMP-compliant processes.

Validation

PPS filters are validated using test procedures that comply with ASTM F 838-15(ae1) protocols for the determination of bacterial retention in filters used for liquid filtration. The challenge level is a minimum of 10⁷ organisms per cm² of filter media. CPF filters have > 7-log removal when challenged with the organisms listed below (0.03μm, 0.10μm and 0.22μm meet the FDA definition of sterilizing grade filters). Validation Guides are available upon request.

0.03μm: Acholeplasma laidlawii
0.10μm: Brevundimonas diminuta
0.22μm: Brevundimonas diminuta
0.45μm: Serratia marcescens
0.65μm: Saccharomyces cerevisiae
