Cytiva, 60110, Supor™ PES membrane disc filter, 0.8 µm, 47 mm, plain, no tab (100/Pk)

Pall Supor polyethersulfone (PES) membrane discs are 47 mm filtration media for laboratory liquid handling and membrane-filter workflows. The 0.8 µm nominal pore size distinguishes these discs from finer 0.45 µm and 0.2 µm members of the Supor PES range. The membranes have a plain, ungridded surface and no handling tab, and each pack contains 100 discs. PES membrane chemistry makes this format useful where hydrophilic filtration media are required. The relatively open pore rating is relevant to clarification or particulate-removal steps rather than validated sterilizing filtration. Use an appropriate 47 mm holder and select membrane pore size based on the particle retention and sample-handling demands of the application.
