UE 50

Summary

Product identification

The TRISEP® UE50 is a polyethersulfone (PES) ultrafiltration membrane with a nominal molecular weight cut-off (M.W.C.O.) of 100,000 Daltons. It is commonly used for the removal of macromolecules or concentration of large organic solutes in both water and process applications. The UE50 membrane sheet is available in wet flat sheet rolls and is FDA compliant.
