Thermo Scientific Slide-A-Lyzer G2 20K MWCO Dialysis Cassettes provide maximum convenience, flexibility and performance for sample dialysis.These second generation (G2) Slide-A-Lyzer Dialysis Cassettes are free-standing, self-floating and pipette-loadable units for dialysis. The single-use, disposable cassettes are available in five different sizes to accommodated samples between 0.1 and 70mL. They offer maximum efficiency, convenience and sample protection in one package. Sample loading and removal are easily accomplished by using a serological pipette or hypodermic needle (optional) attached to a syringe. The built-in air chamber provides sample buoyancy and vertical orientation of the cassette during dialysis.
The 20K molecular-weight cutoff (MWCO) cassettes use a cellulose membrane that is rated to completely retain proteins and other macromolecules that are larger than 20,000 daltons while allowing removal of buffer salts and small contaminants. The membrane is composed of low-binding regenerated cellulose, and the cassettes are manufactured using clean-room conditions.
Easy-loading pipette-accessible for easy sample loading and retrieval
