    Solution Stirring Apparatus

    Overview Products Knowledge Standards Terms
    The solution stirrer uses an electric motor to drive the blades, creating vortices in the liquid to achieve uniform mixing. It is used for dissolving solids, accelerating reactions, or preventing sedimentation, commonly found in laboratory sample preparation and chemical processes.
    Selection
    When selecting, consider the viscosity of the solution and match the stirring power to the container size. For corrosive liquids, use corrosion-resistant materials. Choose a heating function if temperature control is required. Magnetic stirrers are suitable for closed and sterile operations, while mechanical stirrers are better for high-viscosity materials.
