Description

Technical Field

[0001] The utility model relates to the technical field of magnetic stirrers, in particular to a heat-collecting constant-temperature heating magnetic stirrer. Background Art

[0002] A magnetic stirrer is a laboratory instrument used for liquid mixing. It is mainly used to stir or heat low-viscosity liquids or solid-liquid mixtures. The basic principle is to use the principle of magnetic field that like charges repel and opposite charges attract, and use the magnetic field to push the magnetic stirrer placed in the container to rotate in a circle, so as to achieve the purpose of stirring the liquid. In conjunction with the heating temperature control system, the sample temperature can be heated and controlled according to specific experimental requirements, the temperature conditions required by the experimental conditions can be maintained, and the liquid mixing can be ensured to meet the experimental requirements. The magnetic stirrer can be used in biopharmaceuticals, biochemistry, food, nanomaterials, and heavy oil emulsification. It is suitable for laboratory stirring and mixing processes. In biopharmaceutical experiments, the magnetic stirrer is used to stir and mix multiple liquids or liquids and powders to accelerate their mixing.

[0003] When using a magnetic stirrer, the beaker needs to be placed in the middle of the constant temperature heating magnetic stirrer. When the position of the beaker is offset, the magnetic field will push the stirring ring to one side of the beaker, causing the liquid or liquid and powder mixture in the beaker to be stirred unevenly. Furthermore, when producing liquid fertilizer, some liquid fertilizer varieties have high viscosity and high specific gravity, which makes it easier for the beaker to shift during stirring, resulting in uneven stirring. Therefore, the utility model proposes a heat-collecting constant temperature heating magnetic stirrer. Utility Model Content
