The Kelvinox®MX range of wet dilution refrigerators were designed for seamless integration into magnetic and cryogenic environments. The range features interchangeable secondary inserts to allow the system to be configured for a wide range of experimental applications. The KelvinoxMX dilution refrigerator uniquely separates the cooling platform from the experimental services.

  • Flexibility to change experimental configurations and thermodynamic performances, if needed
  • Multiple users to carry out different configured experiments, with minimum downtime
  • Access to different applications by selecting the appropriate experimental insert
  • Simple diagnostics for experimental wiring and set-up can be easily tested
  • All inserts are supplied with a gas handling system enabling automation of the insert cool down

The KelvinoxMX is made up from two main components; a primary insert, that provides a 50 mm line of sight access port, into which a range of interchangeable experimental inserts can be fitted and a dilution unit. 

KelvinoxMX is compatible with the IntegraAC, recondensing liquid helium cryostat. IntegraAC has been developed to significantly reduce the consumption of liquid helium by recondensing helium gas evaporated within the system, which would otherwise be vented from the cryostat. This decreases the frequency of helium refills. Cryogenic systems can be kept cold continuously, even when in stand-by mode, leading to greater freedom to schedule experimental time.

Flexibility: The KelvinoxMX range provides flexibility and modularity for a wide range of applications

Versatile: This is an ideal platform to customise your own experiment

Ease of use: All inserts are supplied with a gas handling system enabling automation of the insert cool down
