What is a PES Filter Cartridge?
A PES (Polyethersulfone) filter cartridge is a membrane-based filter widely used for precision liquid filtration.
Its asymmetric pore structure provides excellent flow rate, low protein binding, and high thermal resistance, making it ideal for biopharmaceuticals, microelectronics, and beverage sterilization.
Características clave:
Asymmetric PES membrane structure
Hydrophilic surface (no pre-wetting required)
Wide chemical compatibility
Long service life and high dirt-holding capacity
Available in 0.1μm, 0.2μm, 0.45μm, 0.65μm pore sizes
