Cryogen-Free Magnetic Refrigerators

kiutra S-Series & L-Series ADR Cryostats

Kiutra believes that magnetic cooling is an extremely versatile and elegant tool to provide low temperatures. They design and manufacture truly cryogen-free magnetic refrigeration systems that stand out due to their high quality, reliability, and ease of use. Being inherently modular, their cryostats can be configured and upgraded to match a wide range of user requirements. And in contrast to many other commercial magnetic refrigerators, their devices offer continuous cooling at sub-Kelvin temperatures.

The cryostats manufactured by kiutra use Adiabatic Demagnetization Refrigeration (ADR) technology to reach sub-Kelvin temperatures either in one-shot or continuous-cooling operation. All kiutra cryostats are built around closed-cycle cryocoolers which provide a base temperature of less than 4 K. These systems may be equipped with up to four ADR stages, and fitted with different cooling media to optimize the cooling power, cooling capacity, and minimum temperature of the system. In this way kiutra cryostats provide single-shot cooling below 100 mK and continuous, cryogen-free cooling down to 300 mK.


kiutra S-Series cryostats

The S-Series cryostats from kiutra pack a lot of cooling power in a small package. These cryostats can be equipped with one or two ADR stages, and one of two cooling media, depending on your cooling needs. Measuring only 75 cm tall and providing a sample space of 320 mm length x 150 mm width x 50 mm height, the S-Series cryostat offers large research possibilities in a small space, and for an affordable budget.

kiutra L-Series cryostats

The L-Series cryostats from kiutra are larger in size, but this allows them to add extra features. For one, these cryostats can be equipped with up to four ADR stages, running in parallel or serially, which allows for several different cooling potentials. In addition, extra add-ons such as an automatic sample changer using a top-loading, load-lock system, allows the user to load samples in just a few minutes and cool them down to base temperature in only a couple of hours. This greatly benefits research in which many samples need to be tested quickly for speedy determination of potential properties. The L-Series measures 115 cm tall (175 cm with sample changer) and uses an innovative puck for its sample stage. These pucks allow you to mount future samples while your current sample is being tested in the cryostat.

L-Series Cryostat Models and Specifications

  • L100g (Continuous: 300 K – 4 K; One Shot: < 1 K)
  • L100f (Continuous: 300 K – 4 K; One Shot: < 0.1 K)
  • L200g (Continuous: 300 K – 1 K; One Shot: < 1 K)
  • L200f (Continuous: 300 K – 0.3 K; One Shot: < 0.1 K)
  • L201f (Continuous: 300 K – 1.5 K; One Shot: < 0.1 K)
  • L302c (Continuous: 300 K – 0.5 K; One Shot: < 0.08 K)
