In 2009, Oxford Instruments not only celebrated 50 years of continuous commitment to science and innovation but also shipped its 50th Cryofree dilution refrigerator. This further demonstrates our position as the market leader of Ultra-Low-Temperature equipment.
Cryofree dilution refrigerators allow you to cool samples to temperatures below 10 mK without the need for liquid helium. Extensive and rapid development of this new technology with high performance to suit demanding Ultra-Low-temperature applications has delivered great success. We have received orders for more than 60 systems, with very positive feedback from our customers.
Professor GAO Jie, Member of the Chinese Academy of Engineering, Laboratory of Mesoscopic and Low-Dimensional Physics, College of Physical Science and Technology, in Sichuan University, China commented: "Our Cryofree dilution refrigerator was delivered four months after placing an order. The installation went very smoothly and the base temperature and cooling power of the insert exceeded the contract specifications. We are delighted with the level of support we got from Oxford Instruments division in China and with the performance of the system. We found that the mechanical and electrical noise levels were very low. We were able to perform highly sensitive measurements at pA current level with no readily perceivable interference from the Cryofree dilution refrigerator."
Cryofree dilution refrigerators can now be integrated with Cryofree magnet systems with magnetic field (up to 15 T) all within the same cryostat. Having an integrated system means the system can be run from one single pulse tube cooler saving on running and maintenance costs and limiting the noise.
