Hydrophilic Flat Sheet Polyethersulfone (PES) Membranes For IV Filtration Products

PES membrane is porous filter media made of pure Polyethersulfone with an asymmetric pore structure that enables retention of micro-particles larger than related pore-size at the surface of the membrane meanwhile allowing maximum throughput. PES membranes are inherently hydrophilic membranes and have high flow rates, low protein and drug binding, broad pH tolerance and high thermal stability. Formats of the polyethersulfone (PES) membranes we supply are available in flat sheets, discs and rolls, with pore sizes ranging from 0.1 to 5 microns, and conform to ISO sanitary standards for pharmaceutical, healthcare and life-sciences filtration applications. Every batch of sample and bulk are tested before handed over to our clients and the quality control process gurantees lot to lot quality consistency in terms of porosity, physical and chemical filtration properties.

If you need assistance to choose the most-suited pore size for your devices and application, please feel free to reach out to us and our team of technicians are always there for you.

Applications

PES membrane is a versatile membrane providing rapid flow and high retention efficiency, it is ideal for sterilization use in small medical filter devices of infusion and transfusion therapy, for example the IV filters. And because of its outstanding characteristics such as low protein absorption and high thermal stability, PES membranes are also extensively used in the healthcare industry for protein separation, monoclonal antibodies, vaccine production and other microbiological fluid filtrations.
