Description

Fluorodyne™ II DFL membrane filter cartridges, part of our Pall filtration portfolio, are 0.2 micron-rated sterilizing grade filters.
These filters retain Brevundimonas diminuta (ATCC 19146) at 10 7 CFU/cm² effective filter area (EFA) and ensure very low extractables and adsorption. They are recommended for sterilizing filtration of pharmaceutical fluids including solutions with active ingredients, biologicals, biotech proteins, ophthalmics and other dilute preservative solutions.
Standard AB-style filters are replaceable cartridges used with stainless steel housing assemblies, suitable for medium-to-large-scale manufacturing operations (100 L to > 1000 L), featuring 226 O-rings as standard. These cartridges are also available encapsulated in the Kleenpak™ Nova capsule format.

FAQs

Question: What are the filter's key dimensions and rating?

Answer:The cartridge is 5 inches (127 mm) long, rated at 0.2 µm, and has 2,700 cm² of effective filtration area.

Question: What connection and seals are supplied?

Answer:It uses double silicone O-rings with a bayonet-lock connection and a fin end; the filter housing must match this geometry.

Question: Does the 0.2 µm designation eliminate process validation?

Answer:No. Sterilizing-grade filtration requires appropriate application-specific validation, compatible process conditions, and integrity testing.

Application Note

Cytiva Pall Fluorodyne II DFL membrane filter cartridges provide 0.2 µm-rated sterilizing filtration for compatible pharmaceutical and bioprocess liquid streams. The 5-inch (127 mm) filter cartridge has an effective filtration area of 2,700 cm² and uses a double silicone O-ring connection with bayonet lock and fin end. This geometry is intended for a matching filter housing; nominal length and membrane rating alone are insufficient to establish interchangeability. Fluorodyne II DFL is designed for low extractables, low product adsorption, and high protein transmission in appropriately validated processes. Filter-family testing against Brevundimonas diminuta and membrane integrity checks support its sterilizing-grade classification, while process-specific validation remains necessary for the actual fluid, operating conditions, and required sterility assurance. Confirm material and fluid compatibility before installation, prepare the assembly using approved wetting and sterilization procedures, and perform the prescribed pre-use or post-use integrity tests when applicable. Monitor filtration pressure and throughput while maintaining documented batch traceability.
