Slide-A-Lyzer G2 Dialysis Cassettes (20K MWCO) provide maximum convenience, flexibility, and performance for sample dialysis.

Slide-A-Lyzer G2 Dialysis Cassettes allow samples to be directly injected with a syringe or pipette through the unique sample port. The cassette design allows air to be removed from inside the cassette to maximize the surface area-to-volume ratio, providing better dialysis performance than dialysis tubing and tube-based systems. The sample is easily recovered through either the pipette or syringe sample ports.

The 20K molecular-weight cut off (MWCO) cassettes use a cellulose membrane that is rated to completely retain proteins and other macromolecules larger than 20,000 Daltons while allowing removal of buffer salts and small contaminants. The cassette membrane is composed of low-binding regenerated cellulose. Membranes and cassettes are manufactured using clean-room conditions to ensure they are contaminant-free.

Features of Slide-A-Lyzer G2 Dialysis Cassettes (20K MWCO):
Easy-loading—pipette-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
Multiple sizes—cassette capacities to optimally match 0.5 to 70 mL sample volumes
Versatile—ideal for removing low-molecular weight contaminants, performing buffer exchange and desalting

Volume ranges:
• 0.5 mL = 0.25 to 0.75 mL
• 3 mL = 1 to 3 mL
• 15 mL = 5 to 15 mL
• 30 mL = 10 to 30 mL
• 70 mL = 25 to 70 mL
