Unit Size: Each
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. 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 via any one of the four corner injection ports • Four cassette sizes—select the cassette that best suits your sample volume • Color-coded—green cassette frame specifies cassettes with the 7,000 MW pore size membrane Membrane specifications: • Composition: regenerated cellulose synthesized by the viscose method • Thickness: 0.9 to 1.2 mil (22.5 to 30 μm) • Hydration time required before use: 2 minutes • Glycerol content: 13% • Sulfur content: 0.1 to 0.15% • Heavy metals content: trace Volume ranges: • 0.5 mL = 0.1 to 0.5 mL • 3 mL = 0.5 to 3 mL • 12 mL = 3 to 12 mL
