The world's coldest, continuous, dry dilution refrigerator, with base temperature of < 5 mK, temperature control range up to 30 K, and cooling powers of > 25 µW at 20 mK and > 850 µW at 100 mK.
Dry systems do not require the use of cryogenic liquids to provide the 4 K environment. Instead, pulse tube refrigerators are used. These enable push-button operation, can reduce the cost of ownership, and negate the need for a helium liquefier.
Our Cryofree® (cryogen free) range of products provides the user with much more experimental space and a larger sample plate, due to not needing a dewar surrounding the system containing the liquid helium for cooling. Mechanical vibrations from the pulse tube refrigerator are significantly reduced using a comprehensive range of vibration isolation techniques.
Uncover the quantum nature of heat, with applications towards quantum refrigerators and improved ultra low temperature thermometry.
Investigate exotic quantum states such as Majorana Fermions and Fibonacci Particles for next generation qubit development.
Lower temperatures reduce measurement errors to enable further improvements in metrological standards.

Reduce noise for lower electron temperatures with cold, low pass filtering.
In addition to the screened measurement cable there is a low-pass multi-stage filter can be mounted at cryogenic temperatures down to below 100 mK. This has the ability to filter 24 signal lines with filter options of 4 different cut-off frequencies. The filter is constructed in an Au plated Cu chassis with RF gaskets to provide screening and thermal dumping for the filter PCB. The filter components are carefully selected surface mount components which provide very good value stability over the temperature range from ambient to sub 100 mK.
In combination with our ultra-low vibration platform, our actively cancelled magnets enable reduced eddy current heating due to vibration at static field for the lowest possible base temperatures. Eddy current heating during sweeping field is also significantly reduced.
Our actively cancelled magnets reduce magnetic field strength at the mixing chamber to less than 10 mT, whilst also reducing the stray field in the external environment and are recommended for all of our 5 mK magnet systems.
