Single-Stage Cryogenic Refrigerator Based on the Gifford-McMahon Principle
The Micromeritics Cryostat I is a closed-cycle cryocooler based on the Gifford-McMahon (GM) refrigeration principle. It uses helium gas from a helium compressor to generate cryogenic temperatures.
The Cryostat I eliminates the need for liquid nitrogen and can obtain temperatures below the 77 K of liquid nitrogen.
