Sartorius Stedim Biotech G has expanded its array of ultrafilters by the Sartocon ECO series of ultrafilters. The filters have been developed for biotechnological and pharmaceutical purification processes in the industry for the manufacture of vaccines and monoclonal antibodies. Sartocon ECO is based on Hydrosart ultrafilter technology that uses stabilized polymer membranes based on hydrophilic regenerated cellulose. Hydrosart membranes enable especially high yields by minimizing protein binding to the membrane and are thus virtually non-fouling. Sartocon ECO ultrafilters will be available in Slice, Sartocon, and Sartocube formats for preferred nominal molecular weight cutoffs of 10kD, 30kD, and 100kD in a cassette design.
