Ultrafiltration Membrane Disc, Ultracel PLTK, RC, 30 kDa NMWL, 90 mm, 5 pc/PAK

Assemble your Amicon Stirred Cell with the membrane of your choice. Ultrafiltration cut disc membranes are available in Ultracel® regenerated cellulose and Biomax® polyethersulvone (PES). The membranes are available in a range of different pore sizes & diameters.
Ultracel regenerated cellulose membranes are recommended for concentrating or desalting dilute solutions. The hydrophilic, tight microstructure of Ultracel membranes assures the highest possible retention with the lowest possible adsorption of protein, DNA or other macromolecules.
Biomax PES membranes are recommended for concentrating or desalting higher volumes of more concentrated samples such as serum, plasma, or conditioned tissue culture media. Microfiltration Durapore® PVDF cut discs are available 0.1 µm, 0.22 µm, and 0.45 µm pore sizes in both 63.5 mm and 75 mm diameters.
