Thermo Scientific™ Slide-A-Lyzer™ Dialysis Cassettes, 7K MWCO
Shop All Thermo Scientific ProductsDescription
Slide-A-Lyzer Dialysis Cassettes (7K MWCO) facilitate the simple and effective removal of salts and small contaminants from proteins or other macromolecules greater than 7,000 Daltons. They are available in four sizes to accommodate sample volumes between 0.5 and 12 mL. These devices are easier to use than traditional dialysis tubing, providing faster buffer exchange, and more complete sample recovery.
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
