Slide-A-Lyzer™ Dialysis Cassettes, 3.5K MWCO (Thermo Scientific™)

Slide-A-Lyzer Dialysis Cassettes (3.5K MWCO) facilitate simple and effective removal of salts and small contaminants from proteins and other macromolecules larger than 3,500 Daltons. They can be used for a wide range of applications including low-molecular weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, and sample concentration.

Key Features

Liquid samples are easily added and removed by penetrating the self-sealing gasket with a hypodermic needle attached to a syringe. No knots, clips, or caps are needed to seal the units and prevent leaking and sample loss during the dialysis procedure. Slide-A-Lyzer Dialysis Cassettes are constructed from two sheets of low-binding, regenerated-cellulose dialysis membrane that are hermetically sealed on either side of a silicone-like gasket inside an inert plastic frame. The membrane and cassette materials are compatible with most common laboratory chemicals and buffers.

Features of Slide-A-Lyzer Dialysis Cassettes:
Easy to use—no knots or clamps are needed; just inject sample into cassette and begin dialysis
Fast dialysis—flat cassette chamber with two membranes provides high surface area-to-volume ratio that maximizes diffusion rate compared to cylindrical dialysis tubing
High recovery—rectangular cassette design maximizes recovery of entire sample volume from any one of the four corner injection ports
Four cassette sizes—select the cassette that best suits your sample volume (0.5 to 30 mL)
Color-coded—pink cassette frame specifies cassettes with the 3,500 MW pore size membrane
