Ready-to-use unit for small volume centrifugal ultrafiltration
  • Separate proteins from low molecular weight substances in biological samples
  • Reverse centrifugal concentration process prevents premature blockage of the filter
  • Unique design can be used in fixed-angle or swinging-bucket rotors accepting standard 15 ml tubes
  • Ultrafiltration of 90% of the original sample volume is typically completed in about 30 minutes
  • Ultrafiltrate is collected in the floater insert tube, where it is accessible without removing the tube
Removal of proteins from biological samples is a critical step for many applications, including:
  • Drug binding studies
  • Determination of metabolites in serum
  • Protein removal from blood samples
  • Cleaning of liposomes
  • Virus removal
