Converse Concentration Deivces

 

Ultrafiltration is the separation process of macromolecular species and solvents based on their size. Converse devices are a particularly favourable methodology due to their flexibility and efficiency as well as the very gentle treatment of the sample solution compared to other orientations. It is a key process in Proteomics as a useful method to purify and concentrate protein solutions.


The Swissci Converse has been carefully designed to maximise the benefits of ultrafiltration with centrifugation and are well suited for particle laden solutions. The reverse direction of flow compared to standard ultrafiltration combined with the high pressure exerted during centrifugation leads to rapid processing times and excellent sample recovery.

 

The sample is held in the chamber on the upper side of the Ultrafilter and during centrifugation low molecular weights are forced through the membrane into a filtrate container on the inner side of the device configuration. The size that passes through the membrane is determined by its Molecular Weight Cut Off (MWCO). Swissci Converse come with specially selected membranes with MWCOs of 3, 10, 30 or 100kDa, others are available upon request. The Swissci Converse is ideal for larger sample solutions of up to 20ml.
