Pleated Filter Cartidge PTFE
Pleated Filter Cartidge PTFE are made up of poly tetrafluoroethylene. PTFE is characterized by high chemical inertness. These are specifically designed for sterile filtration applications of liquid, air & gas streams. They are certified, bio-safe, non-pyrogenic & fully validated to pharmaceutical standards. PTFE, the unique material used in cartridge manufacturing are chemically inert, not shedding and biologically safe according to F.D.A., USP and EEC requirements for pharmaceutical and food contact usages. Pleated Filter Cartidge PTFE is used in filtering the highly corrosive solutions such as strong acids, base solution, and solvents. The cartridge has about 80 – 95 % porosity & uniform pore size distribution. Moreover, the filtration area of each cartridge is as high as 0.7 m2. Therefore, it offers a high flow rate, low-pressure drop & long service life. These can be steam sterilized directly or reverse as per standardized operating data.
