PES Pleated Filter Cartridges (SulfoFil)

Vens SulfoFil cartridges use a hydrophilic polyethersulfone (PES) membrane with a graded pore structure and polypropylene parts, hot-melt sealed with no adhesives or surfactants. They stand repeated steam sterilisation and hot-water sanitising, bind little protein, and remove particles and bacteria from liquids and gases.
