Cytiva Vivaspin 20 Protein Concentrator Disposable Spin Column, 20 mL, 14 mL, 50000, PES Material,

Cytiva Vivaspin 20 Protein Concentrator Disposable Spin Column, 20 mL, 14 mL, 50000, PES Material, <20 uL, 50 uL, Polycarbonate. Vivaspin ultrafiltration spin columns are designed for fast, non-denaturing concentration and desalting of proteins and other biological samples. Membrane spin columns such as Vivaspin combine the principle of size exclusion with centrifugation to achieve rapid concentration and high recovery of target biomolecules in a single tube. An upper compartment containing sample is separated from the lower compartment by a semi-permeable membrane with an appropriate MWCO value chosen to exclude molecules of interest. Centrifugation is applied to force solvent through the membrane, leaving a more concentrated sample in the upper chamber. The Vivaspin column design permits protocols for one-step biomolecule concentration, rapid sample recovery (reverse spin protocol), desalting and buffer exchange - GHC-F (Additional S&H or Hazmat Fees May Apply)
