PES(Hydrophilic) Membrane Filter

A PES membrane filter is a common membrane and the world’s advanced microporous filter membrane. Most of its solutions can provide excellent performance for the purpose of retention and recovery. PES membrane filter is characterized by non-hydrophobic or hydrophilic interaction, low pollution, wide fluid range and pH range, which is usually the preferred membrane filter in the filter process. PES hydrophilic filter membrane is made of pure polyether sulfone material, without supporting material. It has good mechanical strength, thermal stability, and wide chemical compatibility. It is suitable for pure water filtration, medium filtration, buffer fluid filtration, protein solution filtration, biological products sterilization filtration, etc.

PES microfiltration membrane (polyvinylidene fluoride), using the asymmetric structure, uniform openings.PES has excellent heat resistance, physical and mechanical properties, insulation properties, etc. PES microfiltration membrane can ensure low protein adsorption and low dissolution in the filtration process. Hawach Scientific company specializes in the production of PES filter membrane, stable quality, products exported to Europe, North America, and other countries. We have more than 16 years of experience in the filtration industry.
