UH004 P

Summary

Product Identification

The NADIR® UH004 P is an ultrafiltration membrane designed for various applications including food, dairy, process separations, and water purification. It is a hydrophilic polyethersulfone (PES) flat sheet membrane with a nominal molecular weight cut-off (M.W.C.O.) of 4,000 Daltons, offering high rejection of solids. The UH004 membrane is available in dry flat sheet rolls and is FDA compliant.
