Thermoelectric Cold Plate
3" diameter top plate. Cabinet dimensions 7 1/4" x 5 1/2" x 4 3/4". Power requirements 50 watts. This unit uses the most efficient solid state thermoelectric modules yet developed. DC power is supplied to these high powered modules to control temperatures between +25o C and -20o C depending on the set point required. All units may use air cooling with built-in fan, or tap water cooling as the heat exchanger. Equilibrium is reached in 2-3 minutes. Lightweight, portable. Has been used successfully in recrystallizations, freezing point determinations, and temperature control for physical measurements.

Digital Stir Kool, Combination Cold Plate and Stirrer w/GLASS THERMAL PROBE 5"
This unit literally pumps thermal energy down the drain. As power is applied to the rugged thermo-electric modules, heat is transferred from the cold plate to the heat exchanger. The heat exchanger is maintained at tap water temperature by a hose connection to the 1/4 inch tubing at the rear of the instrument. A flow of one liter of tap water per minute through the heat exchanger is sufficient to carry excess heat down the drain. The unit has a low temperature limit approximately 40oC below that of the tap water. The unit is recommended for solutions up to 200ml and uses a 3 inch diameter top plate from which heat is extracted at an initial rate of 130 BTU/hr. There is a built-in magnetic stirrer with speed control which, combined with a magnet bar in the solution, will keep your solution at equilibrium. The digital meter controller is very easy to set. Just follow the simple instructions to dial in the desired temperature for your project. The controller will maintain the set point to +/- 0.1oC accuracy.
