ZNCL-DL 5-Position Intelligent Electric Heating Magnetic Stirrer

What is a Magnetic Stirrer?

A magnetic stirrer is a laboratory device that can create a rotating magnetic field so that the liquid can be stirred automatically and quickly by a magnetic stirring bar. It generally plays a key role in minimizing the risk of contamination since there is only an inert magnet bar that is placed inside the liquid sample. Hence, it can be used in many fields, such as food industry, chemical industry as well as biological field. But the magnetic stirrers are not suitable for stirring large volumes and high-viscosity substances and can only be used in relatively small experiments.

Working Principle of a Magnetic Stirrer

A magnetic stirrer is commonly used in chemical, food, pharmaceutical, cosmetics, environmental protection and other fields. It has a simple operation, and the stirring speed and direction can be adjusted according to the requirements of users. The basic working principle is that like magnetic fields repel each other while unlike ones attract. The magnetic stirrer placed in the container is pushed by the magnetic field for circular operation to stir liquid. With the heating temperature control system, it can heat and control the temperature of the sample according to the specific experimental requirements, and maintain the temperature condition required by the experiment, ensuring that the mixed liquid meets the experimental requirements.

What is a Magnetic Stirrer Used for?

A magnetic stirrer is primarily used for dissolving, heating, and mixing in pharmaceutical, food and other industries. Specially speaking, there are mainly three uses. Firstly, it can make reactants mix evenly and temperature distribute uniformly. Secondly, it can be used to prevent bumping when heating in a closed vessel. Thirdly, it can be used to speed up the reaction or evaporation and thus shorten time.

Why is a Magnetic Stirrer Used?

With a shell made of special flame-retardant reinforced plastic, a magnetic stirrer has a high resistance to heat, acid, alkali and organic solvents. It is widely applicable for the stirring of solvents of different viscosity. Both its stirring speed and heating temperature can be adjusted continuously. Compared to original stirrers, a magnetic stirrer has more advantages. So a magnetic stirrer is widely used in many fields.

What is Magnetic Stirrer with Hot Plate?

The magnetic stirrer with hot plate is also a kind of magnetic stirrer, which is known as the hot plate magnetic stirrer as well. The magnetic bar can be immersed in the liquid to provide the stirring action. The magnetic stirrer with hot plate can keep liquids being stirred automatically as they are heated for a faster reaction.
