Thermo Scientific™ Slide-A-Lyzer™ 7K MWCO G2 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 pipet-loadable units for dialysis. The 7K MWCO units are available in two different sizes to accommodate samples between 0.1 and 3mL. (Cassettes with other MWCO designations are available in five sizes to accommodate up to 70mL). The single-use, disposable Slide-A-Lyzer G2 Cassettes offer maximum efficiency, convenience and sample protection in one package. Sample loading and removal are easily accomplished by using a serological pipet 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 7K molecular-weight cutoff (MWCO) cassettes use a cellulose membrane that is rated to completely retain proteins and other macromolecules that are larger than 7000 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 – pipet-accessible for easy sample loading and retrieval

  • Self-floating – integrated air chambers eliminate the need for float buoys

  • Sturdy construction – ensures the highest possible sample integrity and protection

  • Superior design – thoroughly researched and tested to provide fast and consistent dialysis with maximum sample recovery

  • Two sizes – optimized for 0.1 to 0.5mL samples and 0.5 to 3mL samples, respectively

  • Versatile – ideal for removing low molecular-weight contaminants, performing buffer exchange and desalting
