100ml Capacity and 230V 50/60Hz, 75W CMUA Electromantle
CMUA Electromantles share all the excellent features of the CMU Electromantle, but with the added functionality of magnetic stirring. For convenience and safety, the electric circuitry for stirring is built into the base of the heater, enabling powerful stirring over a wide range of solution volumes and viscosities using a magnetic stir bar.
Magnetic stirring
Stirring operation is simply achieved by placing the correct style and sized magnetic stir bar into the flask, selecting the minimum speed on the stirring dial control, and then ramping up slowly to the required speed. The correct style and size of the stir bar are determined according to the flask volume and the viscosity of its contents.
Stir speed is bi-directional and easily adjustable, and as an added feature, there is an auto-recapture switch fitted. Occasionally, the magnetic coupling to the stir bar may be interrupted and the stirring motion may be temporarily lost. Should there be a need to re-activate stirring, this can be quickly remedied by reducing the stirring speed and then activating the auto-recapture switch; normal stirring can then be resumed at the desired speed.
Electromantle Guide
The Electrothermal series of heating mantles have been specifically designed to provide a comprehensive answer to heating fluids in round bottom flasks in the modern laboratory. The original “Electromantles” revolutionized round bottom flask heating by incorporating a coiled flexible heating element, which ingeniously wraps the heater around the flask to optimize heat transfer. For maximum safety, the flask is held away from direct contact with the heating element via a grounded earth screen. This design principle has stood the test of time and has been imitated the world over. With many years of experience, Electrothermal remains at the forefront of laboratory heating and its associated controlling technology.
