attoDRY
Closed-cycle Cryostats
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
unique instruments with unmatched and proven low mechanical vibrations,
unprecedented low acoustic noise levels, and exceptional temperature
stability.
Besides, our toploading 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 as 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.
Cryogen-free Ultra-low Vibration
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 Silent Operation
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 Fast Cooldown
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.
Versatile Platform Temperature Stability
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 unattend-
ed measurement cycles during your experiment.
