HSGPFP Sterilizing-Grade Gas Filter
Cobetter HSGPFP series filter cartridge is made of PTFE membrane. Its support is made of polyphenylene sulphide and can resist higher temperature. It is widely used in gas sterile filtration in pharmaceutical, biological products, fermentation industry. The intrinsic hydrophobicity as well as 100% integrity testing ensure absolute sterilization.
