PES Membrane
PES membrane is a highly microporous membrane composed of modified polyethersulfone that is a tough, durable, and temperature-resistant aromatic polymer.
PES membrane provides high flow rate, low extractables and greater mechanical strength than competitive membranes. This membrane is specifically designed for biological, analytical, electronic, pharmaceutical, beverage, and sterilizing filtration applications.
PES membrane is available in pore sizes ranging from 0.01 μm to 1.0 μm. It is inherently hydrophilic as standard, but can be made hydrophobic upon request. | Filter Membrane | Hydrophilic PES |
