The Rigaku X-Stream 2000 Cryogenic Crystal Cooler System is manufactured by Rigaku. The X-stream 2000 Cryogenic Crystal Cooler is a self-contained apparatus designed for cooling crystals to a temperature within the range of -180°C to +4°C. The X-stream 2000 system takes room air, compresses it, and removes the impurities from it to produce clean, dry nitrogen. This gas is then cooled to nearly -196°C, and then rewarmed to the desired temperature. The pre-owned products will be thoroughly cleaned and fully tested to perform at manufacturer specifications before shipping.
