Cartridge Filters

These expanded polytetrafluoro-ethylene (ePTFE) membranes housed in high-density polyethylene (HDPE) cartridge filters are available in three versions with retention ratings of  0.1 µm, 30 nm and 20 nm, and they can be used as drop-in replacements for existing filters. They are said to provide superior retention and be capable of achieving a 150–400% improvement in flow capability over the best filter technology currently available (with the same retention rating and flow performance). All non-PTFE components are made of HDPE to ensure low organic and metal ion extractables. The filters are appropriate for high-turnover recirculation filter systems or as the final filter in high-throughput chemical filling and packaging stations, and are suitable for use during the manufacture of high-purity chemicals used in semiconductor and electronics fabrication processes.
