Electromantle Extraction Heater - 3 positions, 250 mL, 230V

Exclusively designed to allow liquids with different boiling points to be heated and/or stirred next to each other|Unique vented airflow ensures the case remains "cool-to-the-touch"|Stir or heat your solutions simultaneously in each position|Accommodate flask capacities from 100 to 1000 mL|Robust construction permits continuous operation of the mantles as required by routine extraction tests|Choice of three or six positions, with or without stirring function|Regulating the heat on these multiposition extraction mantles is simple using the built-in solid-state electronic controls - choose from units with heat only or heater/stirrer combination. Built for versatility, the units accept round-bottom flasks ranging from 100 to 1000 mL. Each mantle position has an independent heater, allowing liquids with different boiling points to be heated alongside each other, up to a maximum element temperature range of 450C. Each independent heater has its own control dial, on/off switch, and indicator light. If applicable, the light also indicates power supplied to stirring function. Units with stirring function allow you 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. The lower part of the unit containing the control equipment is safely separated from the upper heating elements by a well-ventilated air space. A quartz heating element is housed in a thermally insulated cartridge for easy replacement, extending the life of the heater. Powder-coated aluminum surfaces and polypropylene top cover ensure good chemical resistance and easy cleanup.
