PRODUCT OVERVIEW
Designed for low-binding, high-value fluid filtration
These bioburden-reduction polyethersulfone (PES) membrane filter cartridges are engineered to achieve product-level sterility.
The filters feature a single-layer hydrophilic PES membrane with an all-polypropylene component construction. They deliver broad chemical compatibility, high flow rates with low pressure drop, and minimal extractables.
PES media is especially well suited to fluids containing components prone to membrane adsorption. Its low protein-binding property makes PES a preferred option for high-value protein-containing solutions, including vaccines and biotherapeutics.
