Available in four different cassette sizes to accommodate sample volumes between 0.1 and 30mL, 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. 产品特点: Highlights: 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 – purple cassette frame specifies cassettes with the 20,000 MW pore size membrane 20K Dialysis Membrane Specifications: Composition: Regenerated cellulose synthesized by the Viscose method Thickness: 0.9 to 1.2mil (22.5 to 30µm) Hydration Required Before Use: 2 minutes Glycerol Content: None Sulfur Content: 0.04% Heavy Metals Content: Trace |
