The dependance 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 unique instruments with unmatched and proven low mechanical vibrations, unprecedented low acoustic noise levels, and exceptional temperature stability.
Besides, our systems 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, also contributing to a highly professional user experience.
Tired of helium costs? The attoDRY closed-cycle cryostats require no liquid helium at all, and hence liberate the user from the increasingly unreliable and ever-more expensive supply of liquid helium.
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 attoDRY cryostats provide twice the diameter, the attoDRY800 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.
Special care was taken to reduce the acoustic noise of the inherently loud cold heads by an order of magnitude at the most relevant frequencies. This guarantees a pleasant working environment in your lab.
Automation & touchscreen
Routine procedures such as temperature and magnetic field control are fully automated by a clever gas handling system consisting of integrated pumps, valves and electronics. Moreover, the attoDRY800, 1100 & 2100 are the first cryostats featuring an integrated touchscreen for intuitive control even without a PC.
Initial cooldown of a complete toploading system can be as fast as 5-10 hours (without magnet), whereas samples can be cooled within 1-2 hours. The attoDRY800 cryo-optical table with sample in vacuum features a cooldown time of approximately 3 hours.
A variety of measurement options is available, spanning from a fully 3-dimensional double rotator resistivity module to distinguished characterization techniques such as atomic/magnetic force microscopy (AFM/MFM), scanning Hall probe microscopy (SHPM), confocal microscopy (CFM) and micro- Raman.
The attoDRY 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.
