Magnetic stirrer is a device that uses a micro motor to drive a high-temperature and strong magnet to generate a rotating magnetic field, which drives the stirring element inside the container to rotate, in order to heat the solution and achieve sufficient mixing reaction at the set temperature. Therefore, it is widely used in fields such as biology, medicine, chemistry, and chemical engineering. It utilizes the property of magnetic substances that repel each other of the same sex, and drives the magnetic stirrer to rotate by constantly changing the polarity of the two ends of the base .

To extend the use of the product, all motors of the magnetic stirrer are equipped with fan cooling function. Therefore, when conducting heating experiments, especially high-temperature heating tests, the instrument cannot be used solely for heating. The motor must be adjusted to rotate or rotate at medium speed (or idle) to prevent damage to the motor and electrical appliances due to high-temperature radiation. When the environmental humidity is relatively high, there may be induced electricity transmitted through the insulation layer to the shell. Please ground the ground wire to avoid leakage and pay attention to ventilation.
