Fluorodyne® II DBL Membrane Filter Cartridges

These 0.45 micron-rated filters are predominantly used in pre-filtration applications or viscous fluid filtrations. Validated removal of Serratia marcescens (ATCC 14756) with a typical titer reduction (TR) of > 106 ensures that they are also suitable for bioburden control. A serial layer (0.65/0.45 micron) membrane construction allows for high throughputs and high flow rates compared with other 0.45 micron-rated filters.

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). With Code 7 fittings as standard, these cartridges are the most versatile filtration units in Pall’s product range. They are available with a broader range of filtration media than any other filter type. These cartridges are also available encapsulated in the Kleenpak™ Nova capsule format.

Product Summary

Maintaining the Pall standard of high flow rates and high protein transmission, the Fluorodyne® II DBLMembrane0.45 micron bioburden reduction filter cartridges use AB-style filters to provide efficient filtration. This particular unit from the Pall filtration suite is most versatile. Its uses in both prefiltration and bioburden removal produce low extractable levels. All products are integrity tested and do not use surfactants.
