Description of Water/Liquid Prefiltration
Filtration is the fastest way to remove bacteria from the liquid, and all microorganisms and particles can be effectively removed by trapping them in the filter membrane. WECHENFIB PO Syringe Sterilization Filter are unique product of Wuhan Wechange Company. The core filter membrane is made of EVOH nanofibers, with independent intellectual property rights. This PO membrane owns high throughput, high uniformity, high compatibility, high hydrophilicity, very low extract, low non-specific adsorption, excellent solvent resistance and other characteristics. WECHENFIB PO Syringe Sterilization Filter own a variety of diameters (13mm/25mm/33mm), can efficiently remove particulate matter impurities and microorganisms. They can be used in life science, pharmaceutical, food and beverage and other fields for sterilization filtration. PO Syringe Sterilization Filter are packaged individually, sterilized by ethylene oxide or gamma irradiation or autoclaving.
