Proteus X-Spinner Ultrafiltration Concentrators - the first centrifugal concentrator designed with membrane proteins as a key application

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.

  • Cellulose triacetate membrane for very low protein binding
  • Recovery rate of >98 % - even with hydrophobic proteins
  • Sample volumes: 0.1 - 2.5 ml, Hold-up volume: 25 µl
