The Electronic & Digital Magnetic Stirring Heating Mantles HME-IIB/HME-IIIB provide precise temperature control and magnetic stirring for laboratory heating applications. These benchtop units combine heating elements with magnetic stirring capability, offering temperature control from RT+20°C to 250°C with maximum heating capacity up to 450°C. The integrated digital controls enable researchers to maintain consistent heating and mixing conditions for chemical reactions, sample preparation, and analytical procedures.
Available in multiple capacity configurations from 50ml to 10,000ml, these heating mantles accommodate diverse laboratory vessel sizes. The continuous operation capability and variable stirring speed up to 1600 rpm support extended experimental protocols requiring sustained heating and agitation. Digital temperature control eliminates the guesswork associated with analog heating systems, providing reproducible thermal conditions essential for quantitative analyses and standardized procedures.
How It Works
The heating mantles operate through resistive heating elements embedded within the mantle fabric, providing uniform heat distribution around laboratory vessels. Digital temperature controllers monitor and regulate heating power output based on feedback from temperature sensors, maintaining precise thermal conditions. The heating elements can deliver power ranging from 0.08 kW to 0.6 kW depending on capacity requirements.
Magnetic stirring functionality utilizes a rotating magnetic field generated by a motor-driven magnet assembly beneath the heating surface. This magnetic field couples with magnetic stir bars placed within the vessel, creating rotational motion for sample mixing. The variable speed control (0-1600 rpm) allows adjustment of stirring intensity to match viscosity and mixing requirements of different solutions.
The integrated digital control system coordinates both heating and stirring functions, enabling simultaneous temperature control and mechanical agitation. Temperature feedback loops ensure thermal stability while magnetic coupling provides consistent mixing action throughout the heating process.
