MMR manufactures and markets micro-miniature refrigerators and instrumentation for characterizing materials over a wide range of temperatures for physicists, chemists, materials scientists and device engineers. The firm manufactures temperature controlled systems including cryogenic cooling systems and wide-temperature-range thermal stages that are used in materials research in electrical engineering, physics, biology and chemistry. The firm's technology can also be used in the cooling of computer chips, electronic devices, laser diodes, and thermal imaging devices. MMR's President and CEO is a professor emeritus of physics at Stanford University. MMR released an innovative in-office liquid nitrogen generator, the Elan2, in 2003.
