產品名稱：Slide-A-Lyzer Cassettes, 20,000 MW
貨號：Pierce 66003
規格：10/PACK
Thermo Scientific Slide-A-Lyzer Dialysis Cassettes （20K MWCO） facilitate simple and effective removal of buffer salts and small contaminants from proteins and other macromolecules that are larger than 20,000 daltons.
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.
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.
