Cryostation s50

Montana Instruments

The Cryostation C2 is an ultra-stable low temperature closed-cycle cryostat. It remains the leader in its field due to its extremely low vibrations (<5nm), stable thermal performance at base temperature (+/- 5mK), and unparalleled sample and optical access. The Cryostation's large temperature range of 3.2K to 350K enables a wide range of experiments, while a fast cooldown time of less than 2 hours allows researchers to complete multiple measurements in a single day. 

Closed-cycle means no helium is consumed, so users avoid the high costs, uncertain supply, and challenging operation associated with liquid cryogens. The Cryostation utilizes a straightforward user interface and fully-automated control system to make the instrument more productive and efficient. With this turn-key system, simply set the target temperature and the Cryostation will do the rest. 

A variety of accessories and add-ons allow users to configure the instrument for unique experimental requirements.

Re-Optimized for Reliability
A redesigned nested structure improves stiffness for better positional stability and increased thermal performance. Other design innovations result in even less energy transfer to the table, paving the way for seamless optical integration.

Re-Designed for Simplicity
The new shape to the system bezel improves access to your experiment from all directions. An integrated light makes it easier to see and work with the sample without having to change the rest of the environment.

Re-Calibrated for Control
New updates in the firmware and electronics result in more intuitive temperature control, optimized wide-range temperature stability, and quicker speeds to set-point. The matured system enhances reliability and mitigates external influences, making this the most consistent and user-friendly system on the market.

Magneto-Optic - Integrated magnet options

We've taken the standard Cryostation, with all its stability, and added a 1 Tesla magnetic field with incredible optical access and experiment flexibility. Optical access through the poles, high NA access from the sides, and low working distance access from the top make demanding magneto-optic applications simple to setup. Nano-positioning of the sample is possible inside the magnetic field to make this an even more powerful product!

The Magneto-Optic module inserts magnet poles into two of the optical ports. The pole spacing is adjustable down to 12mm. The magnet poles may have a bore through the core to allow laser illumination of the sample. This preserves optical access from all four sides, as well as the top. The field strength depends on the configuration used. System includes the power supply and water cooling for the magnet.

The Magneto-Optic module has the unique feature that the sample space and poles can be removed from the cryostat and the magnetic system operated without the cryocooler functions.

Electrical Access - Built-in interfacing capabilities

In addition to the included four thermometers and three heaters, the user is provided with 20 electrical connections into the sample area terminating with three miniature connectors. An additonal 8 connections can be configured to be available for the user. Thermal lagging locations for multiple wires are provided so that the sample stage temperature is maintained.


Optical Access - Low working distance & high NA options

The Cryostation provides an unobstructed sample space with 4 radial optical access ports for spectroscopic measurements and 1 top port for overhead microscopy. Both the side and overhead windows can be configured for low working distance imaging. In addition, the Cryo-Optic Microscope add-on module provides an integrated high NA objective held at low temperature to optimize drift and stability. 


Sample Access - Unobstructed access for easy setup

Experimental setup and room temperature measurements in the Cryostation can be done with the sample area completely unobstructed. To continue the experiment at low temperatures, simply replace the radiation shield and vacuum window assembly to begin cooling down. The sample alignment and electrical connections to the sample remain undisturbed.
