Polyethersulfone (PES) This is a general pupose membrane that provides excellent performance with most solutions when retentate recovery is of primary importance. Polyethersulfone membranes exhibt no hydrophobic or hydrophilic interactions and are usually preferred for their low fouling characteristics, exceptional flux and broad pH range. Cellulose triacetate (CTA) High hydrophilic and very low non specific binding characterise this membrane. Cast without any membrane support that could trap or bind passing micro solutes, these membranes are to be preferred for sample cleaning and protein removal and when high recovery of the filtrate solution is of primary importance. Regenerated cellulose (RC) Membrane are also highly hydrophilic and are often preferred for their higher protein recovery when processing some very dilute solutions. Resistance to autoclaving, ease of cleaning and extended chemical resistance also characterises this type of membrane.
