CPF Polyethersulfone Membrane Cartridge, 0.03 Micron Rating, EPS-03, Electronic Grade

EPS cartridges are designed to meet the special needs of the electronics and high purity chemical industries. Polyethersulfone membrane cartridges are resistant to most acids and bases and capable of handling strong sanitization agents. High flow rates make Polyethersulfone a good choice for central DI systems. This membrane will also handle elevated temperatures in compatible fluids. To minimize extractables, each cartridge module is pulsed, power flushed until the rinse effluent reaches 17+ Megohm-cm and less than 3 ppb TOC. Each cartridge module is also individually tested.
