For removing fine and ultrafine particles from aqueous liquids.
EPS Filters provide a wide selection of single-layer Polyethersulfone (PES) cartridge and capsule filters designed for the electronics industry and used for removing fine and ultrafine particles from aqueous liquids. Pore sizes range from 0.02 to 0.45 µm, and the filter devices scale from laboratory to full production using identical materials to ensure consistent results.
The hydrophilic EPS filters have low extractables for fast rinse-up to conductivity limits and fast rinse-down to TOC limits. EPS filters deliver high flow and throughput with chemical compatibility across a wide pH range. They are commonly utilized in the final filtration of liquids for point-of-use tools.
EPS filters are pulse power flushed until the rinse effluent reaches 18+ Megohm-cm and less than 3ppb TOC. Each filter is individually tested to ensure integrity.
