Stirrer is a kind of commonly used equipment in chemical experiment, widely used in chemical industry, medicine, food, paint, paint, environmental protection, cosmetics and other fields. The stirring of the traditional chemical reaction solution is mostly manual operation, which not only consumes manpower, but also causes the phenomenon of uneven stirring of the reaction solution, resulting in inaccurate experimental results. Magnetic stirrer can solve this problem well. The magnetic stirrer is not only easy to operate, but also can adjust the stirring speed and stirring direction according to the operator's wishes, which greatly simplifies the operation process and solves the difficulty of stirring toxic or viscous reaction solutions. Using the same repulsive properties of magnetic substances, the magnetic stirrer is rotated by continuously changing the polarities of both 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, and the second is to heat in a closed container, which needs to prevent bumping For example, in the distillation process, zeolite can be added, or a magnetic stirrer can be used. The third role is to accelerate the reaction rate, or the evaporation rate, and 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.

Tianjin Onuo Instrument Co., Ltd. is a manufacturer that develops and produces laboratory instruments. The produced (Uno) magnetic stirrer is used for heating or heating and stirring at the same time. It is suitable for liquids that are not very viscous, or solid-liquid mixtures. Using the principle of magnetic fields and vortices, after placing the liquid in the container, the The stirrer is put into the liquid at the same time, and when the magnetic field is generated by the base, the stirrer is driven into a circular circulation movement, so as to achieve the purpose of stirring the liquid.
