Fluorodyne® EX EDT Membrane Filter Cartridges

Pall’s Fluorodyne EX grade EDT filter is a highly retentive mycoplasma control filter to be used where the sterility assurance and economical filtration of culture media or other hard-to-filter fluids is paramount.

A unique three-layer construction contributes to outstanding throughput, high flow rates and the superior retention of bacteria and mycoplasma during the filtration of process fluids.

The Pall patented Ultipleat® modular cartridge pleating design in combination with a narrow core ensures high effective filtration areas, small foot-print filter systems and improved process efficiencies. A complete validation package supports the assurance of safety within your process.

Pall’s AB style filters are disposable 254mm (10 inch) modular element cartridges assembled in 254, 508, 762 and 1016 mm lengths to be used with stainless steel housing assemblies, most suitable for medium to large scale manufacturing operations (100 L to >1000 L). With Code 7 fittings as standard, these are the most versatile filtration units in Pall’s range, and incorporate a broader range of filtration media than any other filter type. These filters when encapsulated become the Kleenpak™ Nova capsule format.
