Description
Sample Volume (Metric): 12 mL
Unit Size: Each
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. 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. The membrane and cassette materials are compatible with most common laboratory chemicals and buffers. No knots, clips, or caps are needed to seal the units and prevent leaking and sample loss during the dialysis procedure. Features of Slide-A-Lyzer Dialysis Cassettes: • Color-coded—blue frame specifies cassettes with the 2,000-MW pore-size membrane • Four cassette sizes—select the cassette that best suits your sample volume (0.5 to 30 mL) • 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 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 for normal volumes or 4 minutes for minimal volumes • Glycerol content: none • Sulfur content: 0.169% • 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 • 30 mL = 12 to 30 mL
