PES Membrane Filter Cartridge 

The PES (Polyethersulfone) Membrane Filter Cartridge 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.
