NEW:

ISO Controller utilizes thermoelectric cooling based on the Peltier principle. The unit is designed to maintain a constant temperature between 0 °C and 80 °C when using CO2, N2, and other gases for adsorption analysis. The device rapidly cools and efficiently maintains temperature with minimal electrical current required. The sample area will accommodate up to 3 sample tubes. Heat removal is uniform and accurate when the unit is used with an appropriate liquid (ambient water or liquid antifreeze). The dewar section is placed on the instrument dewar elevator and then raised into position for analysis.

Cryostat I 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 refrigeration effect of the GM cooler results from a series of thermodynamic processes acting on the helium gas that includes: charging and compression, displacement and heat exchange with the regenerator, expansion and heat absorption (cooling effect).
The Cryostat I eliminates the need for liquid nitrogen and can obtain temperatures below the 77 K of liquid nitrogen. The unit is mounted on the Micromeritics instrument with a specially designed fixture. The cold head of the device is positioned at the unit to maintain precise temperature control of the sample tubes. The Cryostat I’s cold head is then connected to a floor mounted compressor
