| Effective filtration area | 800 cm² |
|---|---|
| Inlet connection | 1-1½ in. (25-38 mm) sanitary flange |
| Outlet connection | 1-1½ in. (25-38 mm) sanitary flange |
| Removal Rating (µm) | 0.2 µm |
| Sterilization option(s) | Non-sterile autoclavable |
Answer:800 cm² with a 0.2 µm sterilizing-grade Fluorodyne II DFL membrane.
Answer:The effective area is 800 cm² rather than 3300 cm²; both use sanitary flange connections but require separate capacity evaluations.
Answer:No. This specific capsule is nonsterile and must be prepared under a validated procedure for aseptic filtration.
The Pall Fluorodyne II DFL Kleenpak capsule is a single-use housing fitted with a 0.2 µm sterilizing-grade liquid membrane. This configuration has 800 cm² effective filtration area and 1–1½ inch sanitary flange connections. It provides a compact filtration option for process development, smaller manufacturing batches and transfer operations where the chosen filter area must be justified by throughput and fouling studies. The Fluorodyne II DFL membrane has a different validated function from the Fluorodyne II DBL 0.45 µm bioburden-reduction cartridge. The capsule is supplied nonsterile even though the installed membrane is designated sterilizing grade. For aseptic applications, perform the specified sterilization or preparation steps and apply an appropriate pre-use and post-use integrity-testing strategy. Evaluate the fluid, membrane compatibility, hold-up volume and filtration pressure against the actual process before use.
