In August 2020, Lake Shore Cryotronics acquired Janis Research. The acquisition of the Woburn, MA, based business enables Lake Shore to now offer Janis Research liquid nitrogen (LN2), liquid helium (LHe), and closed-cycle refrigerator (cryogen-free) cryostats, LHe and cryogen-free superconducting magnet systems, cryogenic and cryogen-free probe stations, and various lab cooling systems. This acquisition by Lake Shore does not include the Janis dilution refrigerator or He-3 ultra-low temperature (ULT) system product lines. These will be available from JanisULT, a separate, privately-owned company. Janis combines over 50 years of manufacturing experience with extensive engineering capabilities to provide cryogenic systems for all research applications. Application specific products include cryostats for optical microscopy, FTIR, and Mössbauer spectroscopy, continuous flow and Helium-3 cryostats, 4 K and 10 K closed-cycle refrigerators, dilution refrigerators, superconducting magnet systems, and micromanipulated probe stations. Janis Research offers cryogenic systems for a broad range of applications, with cooling provided by liquid helium, liquid nitrogen or mechanical refrigerators. Each cooling mechanism has distinct advantages and preferred applications, and a Janis Research engineer can assist in choosing the best cooling method for your application.
