Product of the Month September

Proteus X-Spinner 2.5

As Product of the Month of September, we would like to present the ultrafiltration unit Proteus X-Spinner 2.5.
It is the first centrifugal concentrator designed with membrane proteins as a key application.

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 ultra-filtration is in opposite direction to the centrifugal force.
The contra design also ensures that the filter does not clog.
