Ultrafiltration
Ultrafiltration is a fast and simple method for simultaneous concentration of proteins and removal of low molecular weight substances. The unique design of the Proteus X-Spinner Ultrafiltration Concentrators allows not only the efficient purification of membrane proteins, but prevents as well the clogging of the membrane by viscous solutions. Ultrafiltration is done in opposite direction to centrifugal force, thereby minimizing protein loss with diluted or viscous solutions and membrane proteins.
