High Purity – Electronics Grade PES
Hydrophilic Polyethersulfone (PES) Membrane for Electronics Applications

Electronics Grade PES Cartridges are designed to meet the special needs of the electronics industry 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 water systems. This membrane will also handle elevated process temperatures in compatible fluids. Each cartridge is flushed with 18 megohm high purity water to minimize extractables. Each cartridge is also individually integrity tested.
