Thermo Scientific Slide-A-Lyzer Dialysis Cassettes (20K MWCO) facilitate simple and effective removal of buffer salts and small contaminants from proteins and other macromolecules that are larger than 20,000 daltons.

Available in four different cassette sizes to accommodate sample volumes between 0.1 and 30mL, these devices are easier to use than traditional dialysis tubing, providing both faster buffer exchange and more complete sample recovery. Slide-A-Lyzer Cassettes can be used for a wide range of applications including low molecular-weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, and sample concentration.
