Ultrafiltration cut disc membranes are available in Ultracel® regenerated cellulose and Biomax® polyethersulvone (PES).

Ultracel regenerated cellulose membranes are recommended for concentrating or desalting dilute solutions. The hydrophilic and tight microstructure 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.
