Constructed from Foxx’s low-protein-binding, low-extractable hydrophilic polyether sulfone, these filters provide super-fast flow rates and high throughput when filtering media, buffers, and other filtrates common to microbiological and life science applications. PES Disc Filters are available in two porosities: 0.2µm for sterilization and complete bacterial retention, and 0.45µm for particulate removal and clarification. Both porosities are available in industry standard 13, 25, 47, and 90mm diameters. PES Disc Filters are autoclavable and gamma-stable. Foxx’s EZFlow PES Membrane Disc Filters are ideal for use in a wide variety of aqueous filtration applications.
