Available in three different cassette sizes to accommodate sample volumes between 0.1 and 12mL, these devices are easier to use than traditional dialysis tubing, providing both faster buffer exchange and more complete sample recovery. Slide-A-Lyzer Cassettes can be used for a wide range of applications including low molecular-weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, and sample concentration.

The 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. 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.

  • 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 via any one of the four corner injection ports

  • Three cassette sizes—select the cassette that best suits your sample volume

  • Color-coded—green cassette frame specifies cassettes with the 7000 MW pore size membrane
