These centrifugal concentrators offer a simple, one step procedure for concentrating or desalting proteins and other biomolecules with 90% or better recovery.
- Vertical membrane design and thin channel filtration chamber minimises membrane fouling and provides fast, high speed concentrating, even with particle laden solutions
- Integrated dead stop design eliminates risk of spinning to dryness; no respinning necessary
- Low binding polyethersulfone (PES) membranes are available with five molecular weight cut-offs (MWCO): 5000, 10000, 30000, 50000 and 100000 to meet all of your concentrating needs
- Choose an MWCO ½ to ¹/₃ smaller than the protein to be concentrated
- The MWCO and graduations are printed right on the side of the concentrator tube to avoid mix-ups
Choice of three sizes for better 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
Ordering information: 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. Rotors are not included. Please contact Avantor for further information.
