The KelvinoxJT is a small, dipstick-style, dilution refrigerator, which features a Joule-Thomson condensation stage. It means the KelvinoxJT can operate in any 4 K environment – wet or dry – as it does not rely on a 1 K pot. KelvinoxJT is ideal for neutron or X-ray scattering experiments because there is no liquid helium in the sample horizontal plane.

  • Compatible with our Cryofree TeslatronPT, our wet Integra magnet systems, any liquid helium transport dewar or any VTI with a sample tube diameter of at least 50 mm
  • Quick cool-down time: typically 6 hours from room temperature to base
  • Inner vacuum chamber (IVC) with automatic exchange gas control
  • The IVC is sealed using vacuum grease or caff paste (no Indium is required)
  • Wide temperature range: when operated in a VTI, the temperature can be controlled between 25 mK and 300 K
  • One spare 6 mm line-of sight port for installing experimental wiring

FlexibilityCan be used for a wide range of applications

Versatile: Can operate in any 4 K environment – wet or dry

Ease of use : Supplied with a gas handling system enabling automation of the insert cool down

 

Base temperature: 25 mK in a VTI, ≤ 40 mK in 4 K (exchange gas or liquid helium) environment

Base temperature stability: ± 1 mK

Cooling power at 100 mK: ≥ 20 µW

System cooldown from room temperature to < 100 mK: typically 6 hours in a wet environment and 12 hours in a dry environment
