Pharmsteri™ II PES 0.22 Buffer Capsule Filters

Validation Guide

Pharmsteri™ II PES 0.22 buffer capsule filters (Pharmsteri II filters) are made of high-grade, gamma stable polypropylene shell and a hydrophilic polyethersulfone (PES) membrane with nominal pore rating at 0.22 μm. The asymmetric PES membrane is sterilizing grade and meets bacterial retentiveness per ASTM F838. Entegris has a long history of compliance in countries of operation/distribution. Entegris actively reviews products for compliance and conformance with government and customer requirements affecting raw materials/substances that may be used in manufacturing processes.
