產品名稱：Dialysis Cassettes; 10,000 MW, 3-12ML
貨號：Pierce 66810
規格：8/PKG
Thermo Scientific Slide-A-Lyzer Dialysis Cassettes （10K MWCO） facilitate simple and effective removal of buffer salts and small contaminants from proteins and other macromolecules that are larger than 10,000 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.
Gamma-irradiated （Sterile） Dialysis Cassettes:
Gamma-irradiated Slide-A-Lyzer Dialysis Cassettes are ideal for researchers culturing cells and microorganisms; purifying viruses, DNA and RNA; or performing sample preparation for other applications in which sterile conditions are required to minimize the risk of sample contamination. The gamma-irradiated cassettes are treated with 20-36 kGy of gamma radiation, a dosage that has been determined to sterilize the units based on both trypticase soy broth medium for identifying total growth and fluid thioglycollate medium for identifying anaerobic growth.
