Magnetically Heated Stirrer

The magnetic heating stirrer uses a rotating magnet at the bottom to drive the magnetic stir bar inside the container, creating a vortex to achieve liquid mixing, while electromagnetic induction heating provides temperature control. It is used for stirring solutions and heating reactions in the laboratory, commonly seen in chemical and biological sample preparation processes.
Selection
When selecting, consider matching the heating temperature range with sample requirements, ensuring stirring capacity is compatible with container size, noting that speed stability affects mixing effectiveness, verifying material corrosion resistance corresponds to solution properties, and confirming safety features include overheating protection and non-slip bases.
