The Cary Company's configurable electronic grade PTFE pleated membrane cartridges are high-purity, all-fluoropolymer liquid filter cartridges that offer ultra-low extractables for demanding applications in the microelectronics industry. The PFA-440HP hardware provides excellent chemical compatibility at a wide temperature range. Capable of filtering at micron ratings from 0.05 to 10 micron, the PTFE filtration media provides high flow rates at low pressure drops.

Our customizable electronic grade PTFE membrane liquid filter cartridges are ideal for aggressive "wet-etch and clean" applications. An optional semiconductor rinse will deliver extraordinary product cleanliness at levels of TOC extractables below detection limits and metals extractables at less than 20 ppb total. Minimized ionic and TOC extractables are attained through the specialized UPW flush process to reduce the risk of short circuiting which can lower yields of wafers in the semiconductor industry. A wet packing option is available for easy wetting in aqueous applications. Configure the best electronic grade PTFE pleated membrane cartridge for your filtration application here!
