kiutra Cryostats

All our cryostats are built around closed-cycle cryocoolers which provide a base temperature of less than 4 K. Systems are available in two different sizes, “S” and “L”, and may be equipped with up to two or four ADR units for further cooling, respectively. Depending on your needs, each ADR unit can be fitted with different cooling media which determine the cooling power, cooling capacity, and minimum temperature of the system. In this way our cryostats provide single-shot cooling below 100 mK and continuous, cryogen-free cooling down to 300 mK.

kiutra Cryostats can be further customized with various add-ons such as our automatic sample changer, custom wiring, sample magnet, magnetic shielding, 3-axes optical access, or a rapid cooldown switch.

Selected Addons

Automatic Sample Changer

The sample changer add-on is a fully automatic top-loading load-lock system which allows the user to load samples in just a few minutes and cool them down to base temperature in only a couple of hours.

Magnetic Shielding

kiutra develops and manufactures superconducting magnets that are optimized for magnetic refrigeration and pro­vide active stray-field compensation to minimize the residual field at the sample position to a value of typically less than 500 μT. If required, this value can be further reduced by two orders of magnitude with our magnetic shielding add-on.

About kiutra

kiutra is a spin-off from the Technical University of Munich, Germany. Due to our many years of hands-on experience in working with cryogenic systems, at kiutra we are convinced that magnetic cooling is an extremely versatile and elegant tool to provide low temperatures.

Therefore, we devote ourselves to the design and manufacture of truly cryogen-free magnetic refrigeration systems that stand out due to their high quality, reliability, and ease of use. Being inherently modular, our cryostats can be configured and upgraded to match a wide range of user requirements. And in contrast to any other commercial magnetic refrige­rator in the world, our devices offer continuous cooling at sub-Kelvin temperatures. 

kiutra is proud to be a corporate member of the Cryogenic Society of America (CSA) and the International Society for Sample Environment (ISSE).
