What is a Heating Mantle?
A heating mantle refers to a laboratory device used to stir or heat samples in glass vessels according to the specific experimental requirements. It is mainly used for stirring, or simultaneously heating and stirring liquid or solid-liquid mixture with low viscosity. It features high measurement accuracy, low warm-stamping, rapid temperature rising, high temperature, simple operation and durability. The heating mantle is generally regarded as the most ideal instrument to do experiments of heating and stirring under the condition of controlling temperature accurately.
How does a Heating Mantle Work?
The basic principle is that like magnetic fields repel each other while unlike ones attract. The magnetic stirrer placed in the container is pushed by the magnetic field for circular operation to stir liquid. With the heating temperature control system, it can heat and control the temperature of the sample according to the specific experimental requirements, and maintain the temperature condition required by the experiment, ensuring that the mixed liquid meets the experimental requirements.
Uses of a Heating Mantle
Widely used for heating and stirring liquid and other experiments, a heating mantle is an essential instrument for biology, genetics, medicine and health, biochemistry laboratory, analysis laboratory, and education and scientific research.
Temperature Range of Heating Mantle
Normal Heating Mantle: The highest heating temperature can reach 400℃.
High Temperature Heating Mantle: The highest heating temperature is from 800℃ to 1000℃ because the high temperature resistant inner sleeve weaving material is adopted.
Heating Mantle VS. Hot Plate
A heating mantle is known as a special equipment to heat round-bottom flasks for distillation. The shell is hemispherical and the interior is composed of the heating wire, insulating material, heat-insulating material and other materials. The appropriate electric heating mantle can be chosen based on the size of the flask. It is frequently connected to the self-coupling voltage regulator for adjusting the required temperature during the use.
A hot plate is actually an enclosed electric furnace, whose shape is rectangular or round generally and temperature can be adjusted. A hot plate can be placed a great number of heating objects without naked flame. As a type of common equipment, it has been recognized and well-received by domestic laboratory over the last decade. It features good temperature control, high stability, and good security, which can help persons to some problems to a great extent. But its shortcomings can’t be ignored as well, such as high energy consumption, low thermal energy efficiency, small effective area of heating and limited processing samples.
