Chemical Laboratory Magnetic Stirrer

Chemical experimental magnetic stirrers utilize a rotating magnetic field at the base to drive a magnetic stir bar inside the container, enabling liquid mixing and heating. They are used for solution preparation, reaction acceleration, and temperature control, and are commonly employed in laboratory synthesis and sample pretreatment.
Selection
Select the stirring force based on the viscosity of the solution. Use a polytetrafluoroethylene-coated stir bar for highly corrosive environments. Choose a model with temperature control when heating is required, and pay attention to the flatness of the container bottom. The speed range should cover experimental needs while balancing stability and safety protection.
