Cryostat I

Overview

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 77 K of liquid nitrogen.

Cryostat for HPVA II

For extensive hydrogen storage studies at high pressures and low temperatures, the HPVA II can be interfaced with a cryostat to control analysis temperatures down to 30 K with a stability of ±0.003 K. 

The cryostat does not require liquid cryogens for operation; instead, it utilizes the Gifford-McMahon refrigeration cycle, where pressurized helium is supplied from a compressor to produce cold temperatures. 

The HPVA II software communicates directly with the cryostat temperature controller, allowing for precise temperature measurements recorded throughout the adsorption experiment. Generating hydrogen adsorption isotherms at multiple cryogenic temperatures presents researchers the advantage of more accurately calculating the isosteric heats of adsorption of hydrogen on their materials of study.
