EPM Membrane Filter Cartridges are designed to meet the special
needs of the electronics and high purity chemical industries.
Materials of construction were chosen for their compatibility with
chemicals and solvents used in electronics manufacturing. The
cartridges produce minimal extractables when exposed to typical
process chemicals and solvents. Each cartridge module is pulse
power flushed until the rinse effluent reaches 18+ Megohm-cm
and less than 3 ppb TOC. Each cartridge module is also individually
tested to ensure it is integral. These membrane cartridges should
be used when high performance filtration is essential for high
process yields.
