product key technologies
Introduction & Principle
The high power magnetic stirrer is a specialized laboratory instrument designed for liquid mixing, mainly used to stir low-viscosity liquids and solid-liquid mixtures.
Its core working principle is magnetic field coupling non-contact drive. Through the magnetic coupling between the external rotating magnetic field and the stirrer in the container, non-contact power transmission is realized, which avoids the shaft seal leakage problem of traditional mechanical stirring. The magnetic stirrer uses the characteristics of the same-sex repulsion of magnetic materials to promote the rotation of the magnetic stirrer by constantly changing the polarity at both ends of the base.
Application
High power magnetic stirrer is mainly used in experimental analysis and scientific research in the fields of petroleum, chemical industry, medicine and health, environmental protection and so on. It can accurately and stably stir liquid solution in a wide range of stepless speed regulation, especially suitable for small volume sample test.
Function
It has two key functions on liquids:
The base of the magnetic stirrer generates a stable and adjustable magnetic field, and this magnetic field will exert a continuous attractive and repulsive force on the magnetic stir bar placed in the liquid container. Under the action of this magnetic force, the stir bar will perform a regular circular cycle movement in the liquid. As the stir bar rotates continuously, it will drive the surrounding liquid to flow synchronously, thereby promoting the full mixing of different components in the liquid, making the composition and concentration of the liquid uniform throughout, and avoiding local unevenness that may affect experimental results.
The other function is the heating function. The device can heat the liquid while stirring, and the appropriate high temperature can effectively reduce the viscosity of the liquid, accelerate the molecular movement speed of the liquid, and make the mixing process of the liquid faster and more thorough. At the same time, the stable high-temperature environment can also help maintain the stability of the liquid system, ensuring that the uniform state of the liquid can be maintained for a longer time.

The Influencing Factors of Stirrer
Temperature, magnetic field and iron material will affect the residual magnetism of the magnetic stirrer, which will affect the stirring effect of the magnetic stirrer. Therefore, it is recommended to replace the magnetic stirrer timely and regularly. By observing the shape of the stirrer, if there is significant wear, it should be replaced. If you need to check the magnetic force of the permanent magnet in the stirrer, you need to use the magnetometer to detect the residual magnetism of the magnetic stirrer.
