025-00303-00Chiller Dewar Micromeritics’ Chiller Dewar is a closed loop recirculating system that utilizes a high surface area copper coil to provide excellent heat transfer between the dewar and the recirculating liquids. Temperature control is provided through Fan external recirculating bath or chiller bath which are supplied as accessory items. The Chiller Dewar is easily mounted to the system’s elevator using the supplied clamping screw and bar set. The unit comes complete with all necessary fittings and tubing for connection to the recirculating bath. An external RTD is also provided which mounts inside the dewar. The RTD connects to the recirculating bath and ensures that precise temperature control is maintained over the course of the experiment
205-33005-00Iso 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.

067-00000-00Smart VacPrep without Vacuum PumpSmart VacPrep is an advanced six-port system that utilizes vacuum to prepare samples by heating and evacuation. Each of the ports may be operated independently. Samples may be added or removed from degas ports without disturbing the treatment of other samples undergoing preparation. Degassing automatically terminates when the samples have completed all programmed steps.
