Fumasep FKD-PK-75 is a PK reinforced Cation Exchange Membrane (CEM) with low resistance, high selectivity, high mechanical stability, and high stability in caustic environment.

Fumasep FKD-PK-75 membrane comes in a 20cm x 30cm size sheet. The membrane is the light brown foil delivered in wet form (2 wt% NaCl solution).

Fumasep FKD-PK-75 Features:
 

 • Applications: Diffusion dialysis for caustic solutions.
 • Cation Exchange Membrane
 • Thickness: 75 micrometers (2.91 mil)
 • Size: 20cm x 30cm

Fumasep FKD-PK-75 Technical Specification Sheet

Handling:

Keep membrane package closed / sealed when unused. Store, handle and process the membrane in a clean and dust-free area. Use only new and sharp knives or blades, when cutting the membrane. Always wear protective gloves when handling the membrane. Handle with care, be sure not to puncture, crease or scratch the membrane, otherwise leaks will occur. All surfaces in contact with the membrane during handling, inspection, storage and mounting must be smooth and free of sharp projections.

Storage:

Storage for short and medium time scale (hours up to several weeks) may be done in unsealed containers in 0.5 - 2 wt% NaCl solution or comparable neutral pH electrolytes. For storage over a longer time period a sealed container is recommended using afore said electrolyte with biocide to avoid biological fouling.

Pre-Treatment and Conditioning:

If you have any concerns about storage, chemical stability and pretreatment before proceeding, please feel free to contact us for further information.

Please note that a current lead time of one to two weeks is to be expected.
