The Electrothermal Electromantle Extraction Heater/Stirrers from Cole-Parmer offer a unique vented airflow which ensures that the case remains cool to the touch. Users can stir or heat solutions simultaneously in each position. The unit accommodates a variety of round-bottom flask sizes from 100 to 1000 mL. The unit has a robust construction, which permits continuous operation of the mantles, a necessary feature for routine extraction testing. Solid-state electronic controls regulate heat, with each mantle position offering an independent heater. Heat liquids with varying boiling points side by side, up to a maximum element temperature range of 450 C. Each independent heater includes its own control dial, operational switch and indicator light. The stirring function allows users to stir from 50 to 1000 rpm while heating. The three-position models have one stir controller for all three mantles. The six-position models have two stir controllers; one for each set of three mantles. Powder-coated aluminum surfaces and a polypropylene top cover ensure good chemical resistance and easy cleanup.
