DICEUHV
The DICEUHV is a top loading dilution refrigerator with a ultra high vacuum central tube, suitable for SPM experiments. The unique design incorporate a 'D' shaped 1K pot, still and mixing chamber base for increase sample access. The large clear areas available for experimental access are ideally suited for installing an extensive range of electrical wiring options, fibre optics and other cryogenic devices.
The cryostat is designed to hold a sufficient volume of cryogens to allow for a convenient period of experimental operation between refills. It can be constructed from non-magnetic materials with all vacuum seals tested for leak tightness on a mass spectrometer to better than 1 x 10-8mbarL/sec.
