General description

Corning Spin-X UF Concentrators:
  • Corning® 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
  • Integrated dead stop design eliminates the risk of spinning to dryness; no respinning necessary
  • Choice of three sizes for greater flexibility: Spin-X UF 500 for samples up to 500 μL, Spin-X UF 6 for samples up to 6mL, Spin-X UF 20 for samples up to 20 mL (14 mL if using fixed angle rotors)
  • Low binding polyethersulfone (PES) membranes are available with five molecular weight cut-offs (MWCO): 5K, 10K, 30K, 50K and 100K to meet all your concentrating needs. Note: Choose a MWCO one-half to one-third smaller than the protein to be concentrated
  • The MWCO and graduations are printed right on the side of the concentrator tube to avoid confusion

  • Spin-X UF 500 for samples up to 500 μL
  • Spin-X UF 6 for samples up to 6 mL
  • Spin-X UF 20 for samples up to 20 mL (14 mL if using fixed angle rotors)

Note: Spin-X UF 500 concentrators require fixed angle rotors. Minimum rotor angle is 40º


Key Spin-X UF Concentrator Applications:
  • Concentration, desalting of proteins, enzymes, monoclonal antibodies, immunoglobulins
  • Removal of labeled amino acids and nucleotides
  • Deproteinization of samples
  • HPLC sample preparation
  • Recovery of biomolecules from cell culture supernatants, lysates
  • Concentrating virus from cell culture medium
