Chase Research Cryogenics designs and manufactures sub-Kelvin sorption cooler systems for a wide and growing range of scientific and engineering fields. Current applications include astrophysics, quantum technologies, nanotechnology, materials science and life sciences. Our main activity is the design and manufacture of sub-Kelvin sorption coolers, with a strong emphasis on custom design to individual specifications. When pre-cooled to 4K using a liquid helium bath or mechanical cryocooler, our compact sorption coolers can achieve temperatures between 100mK and 1K. Historically, most of our customers have come from the astronomical research community and our sorption coolers have been used in the detector arrays of many ground-breaking experiments. Increasingly, our gas-light systems, which offer great affordability and usability, are cooling many of the new cutting-edge industrial applications of quantum technology. We continue to innovate and extend our product range to offer new possibilities to work at ultra-low temperatures. Our continuous sorption cryocoolers can provide stable sub-kelvin temperatures for extended periods, even months at a time. If you are already working with mechanical coolers at 4K, our systems are a surprisingly affordable way to reach the next level of cool!
