The Janis cryogen-free series probe stations provide the researcher with vacuum and cryogenic probing capabilities without requiring the use of liquid cryogens. 4 K, 10 K and 80 K cryocoolers utilize proven Gifford-McMahon (G-M) technology for reliable and affordable sample cooling. Typical applications include MEMS, nanoscale electronics, superconductivity, ferroelectrics, material sciences and optics.
