Fluorodyne® II DFL Filter Cartridges

These validated 0.2 micron-rated sterilizing grade filters retain Brevundimonas diminuta (ATCC 19146) at 107 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.
 
Pall’s 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.
