Helium3 or 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.
