The LOFMEM-TFA filter cartridge has a pleated membrane design to increase its surface area. The membrane and supportive layers are made from PTFE while the inner core, cage and end connections are made from PFA. The manufacturing process does not use adhesive or wetting agents, thus ensuring the highest purity possible for each individually wrapped cartridge. Typical applications involve aggressive acids, bases organic chemicals and oxidizers.
Having a maximum operating temperature of 338ºF, the LOFMEM-TFA filter cartridges can be autoclaved for 1 hour cycles at 275ºF. The LOFMEM-TFA is provided with 0.10, 0.20, 0.45 and 1.0 μm retentions with cartridge lengths of 10", 20", 30" or 40".
