DGPFMP/GPFMP Sterilizing-grade Gas Filter
Cobetter DGPFMP Series Filter Cartridges are composed of double-layer hydrophobic PTFE membrane and a thick thermal resistant polypropylene core. They are highly recommended for air and gas sterile fltration of pharmaceutical, biopharmaceutical and fermentation industries. Both inherently hydrophobic and 100% integrity testing ensure absolute sterilization.
