Sartorius Stedim Biotech has launched a series of ultrafilters for use in biotechnological and pharmaceutical purification processes for the manufacture of vaccines and monoclonal antibodies.
The Sartocon Eco series is based on Hydrosart ultrafilter technology, which uses stabilised polymer membranes based on hydrophilic regenerated cellulose.
Hydrosart membranes enable especially high yields by minimising protein binding to the membrane and are thus virtually non-fouling.
As Sartocon Eco delivers high stability under strongly alkaline conditions and over wide temperature ranges, it is not only simple to clean but also reusable even after several cleaning cycles, reducing operating costs.
Sartocon Eco filters provide constant process performance, allowing process parameters to be maintained in existing cross-flow systems.
According to Frank Meyeroltmanns, head of product management for cross flow at Sartorius Stedim Biotech, high-performance ultrafilters must meet the following requirements: high yield, minimal adsorption, complete cleanability and compatible use in existing cross-flow systems.
'With the Sartocon Eco ultrafilter series, we are providing production managers and process developers with a product that optimally fulfils these requirements,' he said.
Sartocon Eco ultrafilters will be available in Slice, Sartocon and Sartocube formats for preferred nominal molecular weight cut-offs of 10kD, 30kD and 100kD in a cassette design.
