Polyethersulfone filter, the filter medium is the world's advanced polyethersulfone microporous membrane , polyethersulfone membrane filter pore volume representing 80% of the pore opening ratio , has a unique geometry, improved filtering solution for difficult filtration efficiency and liquidity. Using polyether sulfone, and a combination of two materials melt polypropylene support structure, no adhesive material , the more stringent requirements for the chemical and pharmaceutical industries.
Main features: unique hydrophilic properties, surface active agents and the surface free of lubricants, the solution was filtered to provide a high level of precision and liquid filtration , for a wide range of PH , the protein and the adsorption amount of valuable low biological agents , retention rate, has excellent chemical resistance and thermal stability, strength and good resistance to pressure surges forward and reverse , all products are 100% integrity tested.
