A sturdy Pyrex dewar, fully silvered, with an aluminum base. Measuring 80mm ID x 150mm internal depth, this dewar has a full capacity of 600ml. It is designed for use in the freeze / thaw method of degassing NMR samples (see Technical Data). The large ID allows for easy inspection of the process so that it may be controlled more exactly. An optional styrofoam dewar cap, sold separately, greatly reduces boil-off.
