WFPES

WFPES PES Membrane filter cartridges with hydrophilic polyether sulphone membranes can be delivered in filter rations of 0.04 μm to 1.2 μm. The highly porous, asymmetrical PES-membrane is processed in clean rooms without the use of additives or surface-active substances. All components such as core support, adapter and end caps are made of polypropylene and are FDA-certified like the PES membrane material. WFPES Membrane filter cartridges can be sterilised and are integrity-testable. They can be delivered in the preflushed or integrity-tested version.
