Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a multifunctional ice-hot water bath magnetic stirrer. Background Technique

[0002] In the process of chemical and material synthesis, it is inevitable to dissolve and mix reagent materials with water or other solvents. If stirred by hand alone, it is time-consuming and laborious. Therefore, magnetic stirring plays an important role in the process of chemical and material synthesis. The magnetic stirrer is mainly used for stirring or simultaneously heating and stirring low-viscosity liquids or solid-liquid mixtures. Its basic principle is to utilize the principle of repulsion between like poles and attraction between opposite poles of a magnetic field, and use the magnetic field to drive the magnetic stir bar placed in the container to rotate in a circle, so as to achieve the purpose of stirring the liquid. With the heating temperature control system, the sample temperature can be heated and controlled according to specific experimental requirements, maintaining the temperature conditions required for the experimental conditions and ensuring that the liquid mixture meets the experimental requirements.

[0003] At present, there are two problems in using the magnetic stirrer: one is that many stirrings need to be accompanied by heating or low-temperature water bath conditions, but currently the magnetic stirrer does not have a safe and reliable water bath device; the other is that for low-temperature water bath stirring, the traditional method is to add ice cubes to achieve the cooling purpose, but the temperature cannot be accurately controlled, and new ice cubes need to be added as the ice cubes melt, resulting in great inconvenience for the experimenters to operate.
