Pharmsteri™ PES Capsule Filters
High-Performance Single-Use Capsule Filters for Sterile Filtration and Process Flexibility
Pharmsteri™ PES Capsule Filters deliver superior flow rates and sterility assurance for critical life sciences applications. Constructed with a gamma-stable polypropylene shell and hydrophilic polyethersulfone (PES) membrane, these filters offer broad chemical compatibility and exceptional performance in a compact, single-use design. Available in pore sizes of 0.45 μm, 0.22 μm, and combinations, they enable efficient filtration across a wide range of chemistries, including acids and bases. Their single-use format reduces contamination risk, supports multi-use facilities, and improves process economics by eliminating the need for stainless-steel housings. Each filter is 100% integrity tested and designed for sterilization via autoclaving or gamma irradiation, ensuring reliability and compliance for biopharmaceutical processes.
