The magnetic stirrer is suitable for heating or heating and stirring at the same time. It is suitable for liquids with low viscosity or solid-liquid mixture. Using the principle of magnetic field and vortex, after placing the liquid in the container, the stirrer is placed The liquid, when the base generates a magnetic field, drives the stirrer into circular movement, so as to achieve the purpose of stirring the liquid.
working principle:
Using the same repulsive properties of magnetic substances, the magnetic stirrer is rotated by continuously changing the polarity of the two ends of the base
main function:
The general magnetic stirrer has two functions of stirring and heating, specifically:
The first role is to make the reactants mix evenly and make the temperature uniform,
The second is heating in a closed container, which needs to prevent bumping. For example, during the distillation process, zeolite can be added, or a magnetic stirrer can be used.
The third role is to speed up the reaction, or evaporation rate, shorten the time
Scope of application:
The digital heater has a closed-circuit knob to monitor and adjust the stirring speed. The microprocessor automatically adjusts the motor power to adapt to water quality, viscous solutions and semi-solid solutions. (Organized by China Educational Equipment Purchasing Network)
