Closed-Cycle Cryostats

attoDRY series

The dependence on liquid helium continues to involve heavy logistics, high prices and insecure supplies. Consequently, closed-cycle cryostats are becoming more and more popular in all areas involving measurements at variable or low temperatures. With the attoDRY series, attocube provides cryogen-free cryostats with unmatched and proven low mechanical vibrations, unprecedented low acoustic noise levels, and exceptional temperature stability (read more about why to chose a closed-cycle cryostat here). Hence, the cryostats are especially useful for scientific applications such as microscopy and optical spectroscopy, but also transport measurements.

All closed-cycle cryostats have been optimized for fast turnaround times and hence enable a maximum number of measurement cycles in a minimum amount of time. Superconducting magnets in the form of single solenoids or vector magnets are available for measurements in high magnetic fields. Last but not least, special emphasis has been put into the ease of use through automation of routine procedures such as temperature and magnetic field control.

Tired of helium costs? The attoDRY closed-cycle cryostats require no liquid helium, and hence liberate the user from the increasingly unreliable and ever-more expensive supply of liquid helium.

Ultra-Low Vibration

Due to a proprietary design, mechanical vibrations created by the coldhead are well decoupled from the measurement platform, thus enabling the use of sensitive techniques such as scanning probe microscopy in a dry low temperature environment.

Large Sample Space

While most magnet systems feature only 1" diameter sample space, our toploading closed-cycle cryostats provide twice the diameter, the attoDRY800 optical cryostat even offers more room at about 3" diameter. This leaves ample space for sophisticated cryogenic experiments and is of course compatible with our complete line of measurement options.

Temperature Stability

attocube's closed-cycle cryostats enable precise temperature control over the complete range with a stability measured to be much better than +/- 10 mK at low temperatures. This enables long unattended measurement cycles during your experiment.
