Description

The holy grail in ultrafiltration (UF) is to eliminate sample fouling and to enhance recovery and purity of target protein during concentration or buffer exchange step. The 2.5 ml non-stick UF concentrator provides the highest possible protein recoveries. This is due to two factors: the low protein binding cellulose triacetate (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.

Pack contains 96 X-spinner with MWCO of 100 kDa.
