Description

Technical Field

[0001] This utility model relates to the field of chemical experimental equipment technology, and in particular to a multi-magnetic-source magnetic stirrer. Background Technology

[0002] Magnetic stirrers are indispensable experimental tools in chemical reactions. By using a magnetic field to drive the stir bar to rotate, they effectively mix reactants, ensuring sufficient contact between them and thus improving reaction efficiency and yield. At the same time, magnetic stirrers also possess precise temperature control capabilities, maintaining the specific temperature conditions required for the reaction, which helps in the selectivity and rate control of the reaction.

[0003] However, existing magnetic stirrers have the following problems: First, the temperature control method is mainly heating, and it is not possible to actively cool down. Second, existing magnetic stirrers are only suitable for a single reaction. When multiple reaction vessels need to be magnetically stirred, they can only be stirred separately and multiple times.

[0004] In conclusion, there is an urgent need for a multi-magnetic-source magnetic stirrer to solve the problems existing in the related technologies. Utility Model Content
