Answer:0.45 µm for liquid prefiltration and bioburden reduction.
Answer:A 10-inch cartridge with double silicone O-rings, bayonet lock and fin end.
Answer:No. It is a 0.45 µm bioburden-reduction and prefiltration cartridge.
The Pall Fluorodyne II DBL membrane cartridge is designed for 0.45 µm bioburden reduction and prefiltration in process-liquid streams. Its membrane construction combines a controlled removal rating with low extractables and high protein transmission, which is useful when downstream liquid purity must be improved while preserving valuable product. This 10-inch cartridge uses double silicone O-rings, a bayonet-lock fitting and a finned end, so the corresponding vessel connection must accommodate the specific end-cap configuration. It can be positioned upstream of finer sterilizing-grade membranes to reduce particulate and microbial loading and extend downstream filter capacity. Integrity-testing practices and operating conditions should be established for the full filtration process, including media compatibility, pressure and sanitization requirements. Filter compatibility is not universal: ketone and amide solvents require special consideration. The 0.45 µm designation describes bioburden control rather than a blanket claim of validated sterilizing-grade 0.2 µm liquid filtration. This product is a replaceable cartridge rather than a complete filter housing or capsule.
