At the top of our range of top-loading, closed-cycle cryostat, the attoDRY2100 offers a continuous base temperature of 1.65 K, an automated temperature & magnetic field control from 1.65 K to 300 K and your choice of superconducting magnet. It even allows for full magnetic field even at 300 K with exceptional temperature stability, as well as for field cooling of samples without the need to handle liquid helium. It is hence the best choice as your variable temperature cryostat for any low temperature experiment, be it magnetotransport measurements, confocal microscopy & spectroscopy or scanning probe microscopy.
The integrated touchscreen allows for conveniently setting the desired field (B) and temperature (T) without even using a PC. More elaborate measurement schemes such as programmable sweeps of B and T are easily possible via a USB connection and a LabVIEW interface. The top-loading design enables quick and easy sample exchange, while offering a generous sample space of 49.7 mm in diameter.
The unmatched cooling performance via exchange gas coupling provides an initial cooldown time of the complete system of around 15-20 hours, while the turn-around time during sample exchange is around 5-8 hours.
Last but not least, the closed-cycle cryostat attoDRY2100 was specifically designed to provide an ultra-low vibration measurement platform for cryogenic scanning probe experiments without the need for liquid helium. Due to a proprietary design, mechanical vibrations created by the pulse-tube coldhead are decoupled from the measurement platform. When measured with the attoAFM I, vibration amplitudes of less than 0.15 nm RMS are routinely achieved (bandwidth of 200 Hz, vertical direction).
