The holy grail in ultrafiltration (UF) is to eliminate sample fouling and to
enhance recovery and purity of target proteins 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.
Sample volume is 0.1 - 2.5 ml, hold-up volume is 25 µl.
Trial pack contains the following X-Spinner with MWCOs of: 2 x 5 kDa, 3x 10 kDa, 2x 20 kDa, 3x 100 kDa, 2x 300 kDa.
