The Thermo Scientific™ Slide-A-Lyzer™ Dialysis Cassettes (20,000 MWCO) offer a convenient, efficient, and leak-free method for removing salts, buffer exchange, and small contaminants from proteins and other macromolecules larger than 20 kDa. Designed as an easy-to-use alternative to traditional dialysis tubing, these cassettes deliver faster buffer exchange, higher sample recovery, and greater ease of handling. Available in four volume sizes (0.5 mL, 3 mL, 12 mL, and 30 mL), they support a broad range of laboratory applications.
Key Features & Benefits
- Simple Operation – No knots, clamps, or caps required; self-sealing gasket allows sample injection via syringe.
- Fast Dialysis – Flat, dual-membrane chamber provides a high surface-area-to-volume ratio, enabling rapid diffusion compared to cylindrical tubing.
- High Recovery – Rectangular cassette design with four corner ports ensures complete sample retrieval.
- Four Volume Sizes – Choose the optimal cassette for your sample volume, from 0.5 mL to 30 mL.
- Color-Coded Frames – Purple cassette frame indicates a 20 kDa MWCO membrane for quick identification.
- Broad Chemical Compatibility – Membrane and cassette materials are compatible with most common lab buffers and reagents.
