Overview

The PES (Polyethersulfone) Membrane Capsule Filter is an absolute-rated sterile filtration solution designed to provide exceptional performance for aqueous filtration processes with high purity and reliability. These cartridges utilize a hydrophilic, asymmetric PES membrane that delivers very high retention efficiency, typically achieving up to 99.9999 % bacterial and particulate removal at sterile pore sizes (e.g., 0.1 µm or 0.22 µm), making them ideal for critical sterilization applications.

Housed in durable polypropylene construction and available with advanced media options including PP, PVDF, ACF, and NYLON. This capsule filter performs reliably in both dry and moist conditions. Designed for consistent flow rates, strong chemical resistance, and long service life, it delivers dependable, high-purity filtration where precision matters.

Performance is on par with Cobetter® and Pall® capsule filters, offering comparable quality at a more economical cost.
