Ultrafiltration membranes are generally composed of cellulose or polyethersulfone (PES). The material of choice will greatly depend on sample compatibility and the type of membrane will have a significant impact on performance. The molecular weight (MW) of the macrosolute that is to be retained determines the membrane nominal molecular weight cut-off (NMWCO). The diafiltration technique utilizes ultrafiltration membranes, either in centrifugal or pressure-driven devices such as the Amicon^® Stirred Cell for efficient buffer exchange. The ultrafiltration membranes are preferred over dialysis tubing as the membranes can be used for both sample concentration and buffer exchange. This minimizes sample transfers and reduces sample loss.

Ultrafiltration Discs, 100 kDa NMW has been used:

• in Millipore stirred ultrafiltration cell (MSUC) for glucose/ gluconic acid (GA) conversion catalyzed by glucose oxidase (GO)
• with Amicon^® stirred cell model 8200 for microbial extracellular vesicles (EVs) isolation of large volumes cultures
• in the synthesis of polydopamine (pDA)-modified iron oxide core-shell nanoparticles (IONPs)
