What are the advantages of magnetic stirrer compared to ordinary stirrer

Uses and characteristics of magnetic stirrer

The heating magnetic stirrer adopts high-quality DC motor, which has low noise and stable speed regulation. The fully enclosed heating plate can be used for auxiliary heating. Constant temperature magnetic stirrer can set temperature and temperature display, can be used for long-term heating, and the digital display is intuitive and accurate. The stir bar made of polytetrafluoroethylene and high-quality magnetic steel is resistant to high temperature, abrasion, chemical corrosion and strong magnetism. The mixing work can be carried out in a closed container, which is ideal and convenient to use.

Features: The shell is made of special flame-retardant reinforced plastic injection molding, and the magnetic stirrer has very high resistance to heat, acid, alkali and organic solvents. The magnetic stirrer is widely used in the stirring of solvents of different viscosity, and the stirring speed and heating temperature can be continuously adjusted.

The difference in the definition of magnetic stirrer ordinary stirrer:

From the name, we can see that they are different. However, their power source is completely driven by DC motors (also called motors). Here is a good introduction to their working principle.

The difference in the working principle of the ordinary stirrer:

The working principle of the magnetic stirrer, from the name of it, mentions the magnetic force, where does the magnetic force go? Of course, it needs to pass through the magnet. Utilizing the same-sex repulsion of magnetic materials, the magnetic stirrer is driven to rotate by continuously changing the polarity of the two ends of the base. It is used for liquids that are not very viscous, or solid-liquid mixtures, using the principle of magnetic field and vortex. Some have heating function to meet the temperature requirements in the experiment.

The working principle of the electric stirrer is realized by the direct-current motor (also called motor) spindle driving the stirring knife. The stirring knife is directly installed on the DC motor, and it does not need to be transmitted through anything to directly realize the stirring.

As for the choice of agitator, it should be based on the actual situation, the size of the viscosity, the size of the venue, and the size of each experiment to decide which agitator to choose.
