Cryogen-Free Sub-Kelvin Refrigerators
kiutra L-Type Rapid & S-Type 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.
Models
The L-Type Rapid is a unique top-loading cADR system offering continuous cooling at 300 mK and one-shot operation to 100 mK. Its innovative automatic sample transfer feature allows users to cool a sample to the minimum temperature within less than three hours, thus enabling high-throughput screening of scientific samples and rapid prototyping of quantum electronics. For low-temperature investigations of field-dependent physical properties, the L-Type Rapid can be equipped with a 5T sample magnet.
Features
- Continuous operation at 300 mK
- One-shot cooling to 100 mK
- Operation time: 3 hours at 100 mK
- Sample platform: 36 mm (diameter) x 100 mm (height)
- Optional 5T sample magnet available
- Up to 4 RF connections on a puck
The S-Type Essential is a fully integrated 19" rack mounted cryogenic platform for the continuous, cryogen-free cooling of quantum devices. In its standard configuration, the system provides continuous cooling at 300 mK and "one-shot" operation down to 100 mK – without the need of cryogens. Despite its compact size, the S-Type Essential features a large sample platform to accommodate complex user setups or multiple electronic devices. The System can be adapted to integrate special wiring, fiber-optics, and other custom setups.
Features
- Continuous operation at 300 mK
- One-shot cooling to 100 mK
- Operation time: 3 hours at 100 mK
- Sample platform: 150 x 300 x 100 mm (W x L x H)
- Various wiring options (Up to 48 DC, 16 RF, or 4 optical lines)
The S-Type Optical is a fully integrated 19" rack mounted optical cryogenic platform for the continuous, cryogen-free cooling of optical experiments. The cryostat is designed for a broad range of low-temperature experiments and applications that require simple and fast access to the sample stage. The system offers a unique combination of sub-Kelvin temperatures, automatic operation, and free-beam optical access on a small footprint.
Features
- Optical Free-Beam Access: Ø > 20 mm
- Sub-Kelvin Temperatures
- 3 T Sample Magnet
