Merck, PLCC06210, Regenerated Cellulose Membrane Filter, 5 kDa NMWCO

Ultrafiltration membranes are either made of cellulose or polyethersulfone (PES). These membranes are used in diafiltration, either in centrifugal or pressure-driven devices such as the Amicon® Stirred Cell for efficient buffer exchange. The ultrafiltration membranes can be used for both sample concentration and buffer exchange. This minimizes sample transfers and reduces sample loss.
