Oxford Instruments NanoScience specialises in the manufacture of cryogenic systems such as dilution refrigerators, Helium-3 systems, superconducting magnets and cryostats for spectroscopy measurements and spares parts.

Our technology is used in applications such as characterisation of new materials and devices at the nanoscale, data protection and storage, fusion energy and high temperature superconductor materials.

From the world’s first commercial dilution refrigerator to the 2010 Queen’s Award for Enterprise: Innovation for TritonTM200 (a cryogen-free dilution refrigerator with an integrated high-field superconducting magnet), Oxford Instruments have gained considerable experience in the design and manufacture of the most complex cryogenic systems. In recent years, they have been focusing on the development of our Cryofree® technology to meet the demands of our customers. They have now the most extensive range of cryogen-free products on the market.

Dilution Refrigerators to 5mK

The 3He/4He dilution refrigerator is the only means of providing continuous cooling power at temperatures below ~ 300 mK. Oxford Instruments manufactures a variety of dilution refrigerators suitable for a diverse range of experimental applications, as well as custom solutions for highly specialised installations, such as those requiring UHV. We offer traditional “wet” fridges which require a liquid 4He cooled environment as well as “dry” systems where the cold environment is provided by a closed cycle mechanical cooler. Both wet and dry fridges can be integrated with high-field superconducting magnets.

3He Refrigerators

Temperatures below 250 mK can be attained using 3He refrigerators. Oxford Instruments manufactures both 3He inserts for traditional “wet” cryostats and “dry” systems which use mechanical coolers, such as pulse tube coolers, to provide the cold environment. Oxford Instruments’ systems employ highly-efficient cryogenic sorption pump technology to achieve high pumping speeds at the 3He pot.  These are single shot systems.

Additionally, continuous 3He systems are available which employ room temperature pumps to circulate the 3He in a closed cycle.  Here continuous operation at cooling powers greater than 60 mW at 600 mK can be attained.

Both wet and dry systems can be integrated with high-field superconducting magnets.

4He Refrigerators

  Temperatures below 800 mK and cooling powers greater than 100 mW at 1 K can be attained using 4He refrigerators.

Oxford Instruments manufactures both 4He inserts for traditional “wet” cryostats which consume helium from the main bath (these devices are traditionally known as variable temperature inserts – VTIs) and “dry” systems which use a closed cycle circulation system for the 4He and mechanical coolers, such as pulse tube coolers, to provide the cold environment.
