Technology is Key

Solid-state cooling. Cryogen-free. Hassle-free.

With our easy-to-use and cryogen-free tools kiutra leverages the benefits of cryogen-free magnetic cooling. As the world’s first and only commercial supplier we build cryostats that implement classical “one-shot” adiabatic demagnetization refrigeration (ADR) as well as continuous ADR (cADR) for permanent solid-state cooling at sub-Kelvin temperatures.

One Technology, Many Possibilities.

Material Science

The characterization of matter at low temperatures is essential for both the development of novel functional materials and a profound understanding of basic physical concepts. kiutra offers versatile sub-Kelvin research cryostats and add-ons for the low-temperature analysis of material properties.


Photon sources and detectors are key components for various technical applications. To ensure their optimal performance, cryogenic temperatures in the Kelvin or sometimes even sub-Kelvin temperature range are required. kiutra offers fully integrated and automatic cooling platforms with minimal maintenance requirements for the continuous operation such devices.

Quantum Technologies

Novel devices that allow to control and exploit individual quantum states will pave the way to promising applications such as quantum computing, quantum communication, and quantum sensing. However, complex cooling and high infrastructure demands are slowing down the development and widespread adoption of quantum technologies and prevent us from realizing their full potential. kiutra helps researchers and hardware manufacturers to innovate faster by providing automated cooling solutions that facilitate rapid and focused prototyping of quantum electronics.

Photonics & Optics

Probing matter with light is an important experimental technique to gain insights into fundamental material properties and correlation effects. kiutra offers cryogen-free refrigerators with free-beam optical access to allow a broad range of optical investigation to be carried out at sub-Kelvin temperatures.

Our Mission

A better sub-Kelvin experience

At kiutra, our mission is to provide our research and industry customers with easy-to-use, turnkey cryostats that give them the time to focus on their work rather than on their cryostats. We accelerate the development, testing and pre-characterization of quantum hardware and related electronics by means of fast-cooling tools and innovative sample exchange mechanisms. And our cooling platforms offer continuous sub-Kelvin cooling independent of liquid cooling media, notably independent of rare and costly helium-3. This is essential to provide cryogenic temperatures in a simple, compact, and cost-efficient way, and a prerequisite for a scalable application of quantum electronics.
