Laboratory Cryostats

Beyond the Solvay Cryocooler, our “dry” laboratory cryostats feature modular laboratory interfaces that include an insulating vacuum enclosure with feedthroughs and an actively cooled radiation shield for intercepting blackbody radiation.

These laboratory interfaces are optimized for a variety of applications and measurement types:

 
A full closed cycle cryocooling setup, including a pneumatic Gifford McMahon (GM) cryocooler with temperature sensors, a water-cooled helium compressor, helium hoses, a compact vacuum shroud, and a radiation shield.

X-1 Optical Spectroscopy

Our most versatile benchtop optical cryostat featuring up to five perpendicular windows, the X-1 series is a laboratory workhorse used for optical spectroscopy including Raman, Photoluminescence, Spectrofluorometry, FTIR and more.

X-1 cryostats are modularly outfitted with a wide range of optical windows, instrumentation, and sample holders to meet the needs of the experiment, and can be integrated into various benchtop spectrometers.

Aligned with the optical windows at the top, a sample holder is mounted to the cryocooler’s second cooling stage inside the vacuum shroud.

 

X-3 Transport

When optical access is not required, the X-3 series are fully enclosed to limit parasitic heat loads. Frequent applications include Hall Effect, Superconductivity, Magnetotransport and Resistivity measurements of packaged devices at low temperatures.

These cryostats are built with a variety of instrumentation such as multipin feedthroughs with DC lines, low noise BNC feedthroughs with micro-coaxial cables, high frequency (up to 18 GHz) RF cable assemblies, and semi-rigid cables. Sample holders include LCC and DIP Chip Carriers, and wire-bonding chucks specifically designed for low temperature performance.

The narrow variants (X-3-1) are nonmagnetic and designed for placement into electromagnets and superconducting magnets which are also available from ARS. Sample tails are customizable as small as Ø19mm to maximize field strength.

The X-3 Series cryostat is designed for measurements that do not require optical access.

 

X-12 Magneto-Optics

For magneto-optical measurements, our narrow-gap cryostats combine optical access with a sample chamber suitably sized for placement between electromagnet poles for applications like Hall Effect and MOKE.

The laboratory interface is rotatable, is composed of non-ferromagnetic materials and uses magnetic field independent instrumentation.

X-4 Optical Spectroscopy for Large Samples

Our X-4 Series is a larger version of our X-1 cryostats, offering a spacious sample space and large diameter optical windows for similar spectroscopy measurements.

These cryostats can be used for mounting large samples like 2” wafers, or large equipment like Diamond Anvil Cells (DAC).

X-19 Omniplex, Sample in Vapor

Instead of sharing the same insulating vacuum space as the cryocooler like our other cryostats, the sample is placed in a secondary chamber filled with cryocooled helium vapor. This convective cooling is ideal for samples of poor thermal conductivity and allows rapid sample exchange.

The X-19 Omniplex Series is built in a range of chamber sizes both with and without optical access for Spectroscopy, Neutron Scattering, Mössbauer, and X-Ray Diffraction experiments. They allow for fast sample change; the typical turnaround time is about 30 minutes.
