PES Membrane Filter: 0.1μm-15μm Pore Size, PET Support Layer, Hydrophilic & Low Adsorption

Our company manufacture and supply 100% PES membranes and reinforced PES membranes with PET support layer, and different formats including flat sheets, discs, and rolls are available, allowing manufacturers and researchers to choose the best option for their specific needs. PES membrane adopts a unique preparation process: dry/wet/mixed production, with high flow rate/high throughput resistance to autoclaving/no adsorption of proteins and extracts/no pollution to the sample and so on. Pore size 0.02um /0.03um/0.05um/ 0.1um/ 0.22um / 0.45um / 0.8um/0.65um/1.2um/1.0 um/5.0um. The super-asymmetric pore structure, high pore accuracy, and low protein retention of PES with higher water flux compared to other pores of the same pore size make them very suitable for the preparation of biological samples.

PES membrane filters have a range of outstanding properties that makes them well-suited for use in a variety of applications from medical, bio-pharmaceutical industries to academic research facilities. PES membrane filters are inherently hydrophilic and suitable for use with almost all kinds of aqueous solutions. And PES membranes exhibit low level of protein and drug adsorption, which makes them a good choice for protein and liquid drug filtration applications. PES filter membranes also have excellent chemical resistance, with a pH range of 1 to 14 being well within their capabilities, they are therefore commonly utilized for handling strong bases, alcohols and resistive proteins samples.

Applications

Polyethersulfone (PES) membrane filters possess a range of exceptional properties that make them ideal for a variety of applications in the field of pharmaceuticals processing, medical device manufacturing, and life science research. They are a recommended solution 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.
