The Labconco CentriVap® Aqueous Centrifugal Evaporating System is ideal for biology, microbiology, biochemistry, pharmaceutical research, and analytical chemistry applications. It is used to concentrate small-volume samples in aqueous solution. The system uses centrifugal force with heat and vacuum to rapidly evaporate and condense solvents from biological and analytical samples. Under vacuum (very low pressure), the vapor-liquid equilibrium of the solvent is shifted towards the gas phase, while the sample (DNA, peptide, etc.) remains primarily in the solid phase. The system enables easy removal of solvent with very little stress placed on the solute, resulting in a dry, solid sample (plus salts that were present in the solvent buffer, etc.)
