PES Membrane Filters
Nupore provides both hydrophobic and hydrophilic Polyethersulfone (PES) membranes ranging from 0.1μm to 0.8μm. Their high flow rate, low protein binding and minimal extractables make them a preferred choice for pharmaceutical liquid sterilization and filtration of water and proteinaceous solutions. Being chemically resistant, they can be used with aggressive liquid and solvents.
These are offered as membrane disc filters in various size options: 13mm, 25nn, 47mm, 90mm, 142mm and 293mm
