Fumasep FKS-30 is a non-reinforced Cation Exchange Membrane (CEM) with very low resistance, high selectivity and high stability in pH acidic and basic environment.

Fumasep FKS-30 membrane comes in a 20cm x 30cm size sheet. The membrane is the thin, slightly brown foil, delivered on a backing foil (colourless rigid PET foil). Pull off carefully the membrane (brown) from the backing foil.

Fumasep FKS-30 Features:
 

 • Applications: Electrodialysis for demineralisation, desalination, acid recovery applications and others.
 • Cation Exchange Membrane
 • Thickness: 30 micrometers (1.19 mil)
 • Size: 20cm x 30cm

Handling:

Keep membrane package closed / sealed when unused. Unpack membrane only for direct use and process immediately after opening. Store, handle and process the membrane in a clean and dust-free area. 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 which may get into contact with the membrane during inspection, storage, pretreatment and mounting must be free of sharp edges or angles.

Storage:

Dry Form: Storage for long time scale (more than 12 months) may be done in dry state (sealed container).

Wet Form: Storage for short and medium time scale (hours up to several weeks) may be done in unsealed containers in 0.5 - 1.5 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 ca. 100 ppm biocide (NaN3) to avoid biological fouling.

Pre-Treatment and Conditioning:

The membrane is delivered in H+ form and dry form. Depending on application and cell design,assembling is possible in dry form (without pretreatment) or wet form. Before assembling in wet form put the membrane sample between stabilizing meshes / spacers (in order to avoid curling) in NaCl solution - e.g. 0.5 M NaCl solution at 25°C for 72 hrs exchanging the solution several times. Do not let the membrane dry out since micro-cracks may likely occur during shrinkage.

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.
