VivFlux Membranes

Vivascience membranes are also available in a complete range of formats for stirred cells and other filtration products requiring disc membranes. Polyethersulfone, Cellulose Triacetate and Regenerated Cellulose alternatives are offered with molecular weight cut-offs ranging from 5,000 to 100,000 MWCO. The following tables are a guide to selecting the most appropriate membrane material and MWCO.
