The holy grail in ultrafiltration (UF) is to eliminate sample fouling and to enhance recovery and purity of target protein during the concentration or buffer exchange step. Generon has introduced a 2.5 ml non-stick UF concentrator to provide the highest possible protein recoveries. This is due to 2 factors: the low protein binding CTA membrane and critically, the design of the X-spinner which ensures that ultrafiltration is in opposite direction to the centrifugal force. The contra design also ensures that the filter does not clog. This is the first centrifugal concentrator designed with membrane proteins as a key application.
