Synder Flat Sheet Membrane, FR, PVDF, MF, CF042, 5/Pk

Yes—flat sheet membranes can be cut to fit your stirred cell. For best results, use the stirred cell support disk as a template to trace the correct size, then cut the membrane carefully to match.

Used flat sheet crossflow membranes must be stored wet at all times. If a membrane is allowed to dry out, it can irreversibly lose water permeability and performance.

For storage, place the membrane fully submerged in one of the following solutions:
0.5% formaldehyde solution (helps prevent microbial growth)
1.0% sodium metabisulfite (SMBS) solution -- Replace the SMBS solution monthly to maintain effectiveness

UPDI water (ultrapure deionized water)--Replace the water weekly to reduce contamination and biofouling

Flow characteristics for a spiral element and flat sheet membrane are significantly different and are really only comparable on a qualitative basis. Variability in the membrane manufacturing process, differences in water composition, test procedures, and test equipment, used in a factory, laboratory, or elsewhere, will impact water flux results.

Sterlitech flat sheet crossflow membranes should be stored sealed in the original packaging in a climate-controlled environment, protected from direct light, heat, and temperature extremes. While we recommend using membranes as soon as practical after receipt, most flat sheet membranes can typically be stored for up to one (1) year without affecting performance when stored properly.
