350-33005-00 ISO Controller Micromeritics’ 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.
025-00350-00 Chiller Dewar A closed plumbing system that circulates fluid from a temperature controlled bath into a small Dewar filled with antifreeze in which the sample tubes are immersed.
025-26002-00 Recirculating Bath Temperature range from -28 °C to 200 °C, 230 V, 50 Hz. Refrigerated and heating circulator for temperature control of the Chiller Dewar. Note: Recommended for use with the Chiller Dewar Option 025-00350-00
026-00350-00 Cryostat The Micromeritics Cryostat 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).
