Answer:No. It is a nominal 0.45 µm prefilter that protects downstream sterilizing-grade filters.
Answer:0.65 m² for a 10-inch UB cartridge.
Answer:Resin-bonded glass-fiber composite filter media.
Pall PreFlow UB AB1UB7PH4 is a 10-inch depth-prefiltration cartridge designed to protect downstream membrane filters during biopharmaceutical liquid processing. The UB grade has a nominal 0.45 µm removal rating and uses resin-bonded glass-fiber composite media rather than a sterilizing-grade membrane. This cartridge provides a nominal filter area of 0.65 m² per 10-inch element. Its double 226 silicone O-ring arrangement, bayonet lock, and fin end allow installation in matching cartridge housings. The PreFlow platform is suited to the upstream clarification of suitable serum, vaccine, tissue-culture medium, and protein-containing solutions when particulate loading threatens the throughput of final 0.2 or 0.1 µm filters. The 0.45 µm grade is a prefilter and should not be represented as a standalone validated sterile barrier. Correct housing fit and prefiltration capacity influence filter-train performance.
