Thermo Scientific Slide-A-Lyzer Cassette G2 20K MWCO 70 ml Pack of 6

The Thermo Scientific Slide-A-Lyzer Cassette G2 is a specialized laboratory tool designed for the efficient dialysis and purification of large-volume biological samples. This cassette has a substantial sample capacity of 70 ml, making it suitable for processing significant volumes of solution.

A key feature of this cassette is its 20 kDa (kilodalton) molecular weight cutoff (MWCO). This means the semipermeable membrane is designed to retain molecules with a mass greater than 20 kDa (such as proteins, antibodies, or large nucleic acids) while allowing smaller molecules, like salts, buffers, and small metabolites, to pass freely into the surrounding dialysis buffer. The G2 (Generation 2) design simplifies the dialysis process by eliminating the need for traditional dialysis tubing and providing a convenient, leak-proof system with a built-in air bubble barrier.

The Thermo Scientific Slide-A-Lyzer Cassette G2 is a vital tool in biochemistry and molecular biology for applications such as protein concentration, desalting, and buffer exchange prior to final analysis or purification.
