Spin-X UF 6mL Centrifugal Concentrator, 50,000 MWCO Membrane, 25/Case

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. 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): 5,000, 10,000, 30,000, 50,000 and 100,000 to meet all of your concentrating needs. Choose a MWCO 1/2 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 Spin-X UF 500 concentrators require fixed angle rotors. Minimum rotor angle is 40o. Spin-X UF 500 concentrators are for samples up to 500 μL. The patented vertical membrane design and thin channel filtration chamber (U.S. Patent No. 5,647,990), minimizes membrane fouling and provides fast, high-speed concentrating, even with particle laden solutions. Spin-X UF 6 concentrators can be used with either swinging bucket or fixed angle rotors; minimum rotor angle is 25o. Spin-X UF 6 concentrators are for samples up to 6 mL. Spin-X UF 20 concentrators can be used with either swinging bucket or fixed angle rotors; minimum rotor angle is 25o. Spin-X UF 20 concentrators are for samples up to 20 mL, 14 mL if using fixed angle rotors.
