Reserach Cryostats

Fundamental research in physics, as well as specimen characterization in materials science often require the use of (ultra) low temperatures. Many phenomena also involve the application of high magnetic fields, usually generated by superconducting magnets. attocube provides a broad portfolio of versatile cryostats for sensitive measurements at variable temperatures and extreme conditions. In all of our systems, special care has been taken to reduce vibrations and acoustic noise. Even the most demanding applications such as scanning probe microscopy can be performed without compromising their performance.

Depending on available infrastructure on-site in the customer’s laboratory, cost of initial investment vs. running costs, desired performance and personal preference, attocube offers a broad portfolio of research cryostats. Our customers can choose the appropriate cooling system by required base temperature or temperature range, and optionally upgrade it with their choice of superconducting magnet. In order to provide the perfect system for diverse setups and conditions, the product range covers attoLIQUID and attoDRY cryostats. Due to their low vibration characteristics, these cryostats are predestined to be combined with our microscopes, nanopositioners, cryogenic objectives and interferometric sensors, and thus always offer the perfect conditions for your research tasks.

CUSTOMER FEEDBACK

Prof. A. Holleitner

We are absolutely happy with the cooling performance of the attoDRY2100, both concerning base temperature as well as duration to cool it down from room temperature! Therefore, many thanks for developing such a great system!

CUSTOMER FEEDBACK

Dr. B. Urbaszek

We are pleased with the performance of the attoDRY700. The good mechanical and thermal stability ensures that overnight the selected quantum dot remains within the focus of the objective.

attoDRY1000 has quickly become an integral part of the research equipment in our group. The closed-cycle system is easy to operate while providing for excellent stability, short cool down times and low vibration level for optical spectroscopy of solid-state quantum systems. The compatibility with previous versions of CFM-line microscopes and the plug-and-play operation without cryogenic liquids make attoDRY1000 a really attractive alternative to conventional cryogenic spectroscopy in bath cryostat systems.

CUSTOMER FEEDBACK

Dr. B. Alén Milán

Thanks to the cryogen free operation and superb mechanical and thermal stability, unattended data acquisition overnight had never been so easy. This is very desirable when we perform photon anti-bunching experiments on a single quantum dot. Without any special effort, we have observed that the dot luminescence intensity remains constant within ± 7 percent over ten hours.

CUSTOMER FEEDBACK

Dr. S. Heun

The attoLIQUID3000 with the attoDAMP anti-vibration cabinet has been serving us very well as mK platform for scanning gate microscopy since 2008. Its handling is straightforward and easy, and due to the special 1 K pot design, vibrations are of no big concern even at base temperature.

The compact and extremely stable attoDRY700 is not only a great piece of equipment with respect to its cooling and mechanical performances: its ease-of-use and cryo-free operation allow us to focus fully on the ongoing measurements.

CUSTOMER FEEDBACK

Prof. R. A. Taylor

I have to say we are very pleased with the attoDRY800 and have collected a good deal of data already.

CUSTOMER FEEDBACK

Dr. M. Kroner

The attoDRY800 setup is ideal for phase contrast microscopy as it allows free space optical access to the sample from both sides and makes it easily possible to investigate the transmitted light in momentum and real space excellent!

CUSTOMER FEEDBACK

Prof. M. Atatüre

The delivery of the attoDRY1000 was well within the anticipated time frame, the installation was carried out successfully and since then, the system has given full satisfaction. All quoted specifications were fulfilled or exceeded and the service, maintenance and support have proven to be excellent. The unit has been operational since the first day and continues to function with no interruptions. I can verify that, in contrast to typical liquid systems, the attoDRY1000 continues to operate without the typical interruption of cryogenics refill, allowing data acquisition around the clock for months.
