Medical Microporous PES Membranes For Clarification And Sterile Filtration

PES membrane is a membrane filter designed to remove microbes, bacterias and other contaminants or impurities in aqueous filtrations. Made of hydrophilic Polyethersulfone material, PES membrane has characteristics of high strength, low protein-binding, broad chemical resistance,

dimensional stability, high flow rate and high temperature resistance. It also has broad pH range tolerance of acid and alkali.

Because of its high mechanical properties and broad chemical compatibility, the hydrophilic PES membranes are ideal for clarification and sterilization preparation of pharmaceuticals or infusion solutions. If you choose a 5 μm PES membrane, then micro-organisms and particles larger than the pore size can be all retained while the medical ingredients flows through fast and smoothly.

We manufacture and supply a variety of good quality PES membrane in custom dimensions and formats to suit individual customer application requirements. From bulk rolls, sheets to discs, all can be custom manufactured, with pore size selectable ranging from 0.22 μm to 20 μm. If you need help to choose the right PES membrane for your application, just contact us and our team of technicians are very happy to assist you with the best solution.
