Pharmaceutical Grade Polyethersulfone Filter Catridge

Detailed introduction:

Filters are made of Micro series hydrophilic asymmetric sulfonated PES. They have universal chemical compatibility, pH range 3~11. They feature large throughput and long service life, applicable to bio-pharmacy and other fields. Before delivery, each cartridge has experienced 100% integrity test, to ensure product filter efficiency. NSS cartridges are endurable to repeated online steam or high-pressure disinfection, meeting asepsis requirements of new version GMP.
