TefloFlow? HT Filter Cartridges are composed of a hydrophilic PTFE membrane, polyphenylsulfide (PPS) support layers, and oxidation stabilized polypropylene hardware. This filter is recommended for sterile filtration of liquids in critical high temperature applications or filtration of ozonized water. The cartridge is also available with hydrophobic PTFE media upon request
