Laboratory Rotary Stirrer

The laboratory rotary stirrer drives the stirring paddle to rotate via an electric motor, creating a vortex in liquids or solid-liquid mixtures to achieve uniform mixing, dissolution, or reaction. It is commonly used in processes such as color matching and dispersion in coatings and inks, homogenization of paper pulp, and mixing of plastic masterbatches.
Selection
When selecting, consider the viscosity of the material to match the shape of the paddle: use a spiral type for low-viscosity liquids and an anchor type for high-viscosity materials. Determine the shaft length based on the container size. Choose pneumatic models for explosive environments. For corrosive media, stainless steel material is required. For temperature control needs, use a jacketed reaction vessel.
