CF047 Circular Cell Assembly, Crossflow, 316 SS

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.

The Sterlitech bench-scale crossflow test cells are available in a variety of materials to suit most applications:

• Stainless Steel
• PTFE
• Hastelloy^TM
• Delrin (natural acetal copolymer)
• Acrylic

Addtionally, there are a variety of available o-ring seals including Buna-N, EPDM, Viton, FEP encapsulated Viton, and FFKM (Markez).

Sterlitech recommends to install all plastic fittings by hand using PTFE tape. If a plastic NPT or compression fitting starts to leak during operational testing, tighten the fitting carefully until the leaking stops. Excessive tightening may break the fitting or damage other components.

If the fittings is broken and stuck in the cell top, use a spiral flute extractor bit or similar tool to release the portion of the fitting in the cell top. If the cell top becomes cracked from removal efforts, a replacement can be purchased.

These membrane sizes are intended for use in the bench-scale crossflow test cells offered by Sterlitech. Please see list of flat sheet membranes we offer and their dimensions:
