Digital Vortex Stirrer

The digital magnetic stirrer uses electromagnetic induction to rotate a magnetic stir bar inside a container, creating a vortex to achieve liquid mixing. It is used for dissolving laboratory samples, accelerating reactions, and, in the coatings and inks industry, for viscosity adjustment in conjunction with a heating plate.
Selection
When selecting, consider matching the sample viscosity with the rotational speed range, ensuring the heating temperature covers experimental requirements, and the stir bar shape fits the curvature of the container's bottom. Pay attention to the material's corrosion resistance, the suitability of the timer function for prolonged reactions, and stable operation to prevent solution splashing.
