Spin-X UF centrifugal concentrators offer a simple, one step procedure for concentrating or desalting proteins and other biomolecules with 90% or better recovery.

  • The vertical membrane design and thin channel filtration chamber minimizes membrane fouling and provides fast, high speed concen­trat­ing, even with particle laden solutions.
  • Low binding polyethersulfone (PES) membranes are available with five molecular weight cut-offs (MWCO): 5,000, 10,000, 30,000, 50,000, and 100,000 to meet all of your concentrating needs. Choose an MWCO half to a third smaller than the protein to be concentrated.
  • The MWCO and graduations are printed on the side of the concentrator tube to avoid mix-ups.
  • Spin-X UF 6 and 20 concentrators can be used with either swinging bucket or fixed angle rotors. Spin-X UF 500 con­centrators require fixed angle rotors.
