New Corning Spin-X UF Concentrators

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 greater efficiency and recovery.


Key Features & Benefits:

- The patented vertical membrane design and thin channel filtration chamber (U.S. Patent No. 5,647,990), minimizes membrane fouling and provides for rapid concentrating, even with particle laden solutions.
- Integrated dead stop design eliminates risk of spinning to dryness.
- 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 6 mL
       - 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): 5,000, 10,000, 30,000, 50,000 and 100,000 to meet all of your concentrating needs. Choose a MWCO one-half to one-third smaller than the protein to be concentrated.
- The MWCO is printed on the concentrator 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.
