PES (polyethersulfone) membrane:

• PES is considered the best membrane for cell culture fluids. It has the lowest protein binding to maintain protein balance and the lowest extractables to maintain media purity.
• The asymmetric PES membrane and unique Rapid-Flow membrane support system allow fast flow rates and large total throughput for increased filtration efficiency.
• Use 0,2μm membranes for sterile filtration, 0,45μm membranes for liquid clarification and particle removal
