kiutra Cryostats

Cryogen-free Magnetic Refrigerators

All kiutra Cryostats are built around closed-cycle cryocoolers which provide a base temperature of less than 4 K. Depending on your needs, the system may be equipped with up to four ADR stages,  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.

  • Cryogen-free operation
  • Active stray-field compensation
  • Large temperature range (300 K - 80 mK)
  • Fully automatic and robust
  • Modular assembly and upgrades

Available Add-ons

kiutra Cryostats can be equipped with a number of add-ons to offer dedicated solutions for various applications.

Rapid Cooldown Switch

An additional thermal switch reduces the sample cooldown time and facilitates rapid prototyping and large sample turnovers.

Custom Wiring

kiutra offers various kinds of wiring such as DC and RF lines, or fiber optics.

3-Axes Optical Access

In combination with our S100g cryostat, kiutra offers the possibility for direct 3-axis optical access below 1K.

Magnetic Shielding

Mu-Metal shielding reduces the magnetic stray field at the sample position by two orders of magnitude.
