The Spiral Stirrer is used at a low to medium speed in medium to high viscosity fluids. With an axial flow (drawing from the bottom to the top) the Spiral Stirrer is ideal for homogenous mixing and for cooldown phases with heat exchange from bottom to top. The Spiral Stirrer is very good for even distribution of particles (exfoliating beads, active particle beads) and pigments throughout a product. Can be used with sensitive materials. Suitable for emulsions, suspensions, gels, color cosmetics.
The Anchor Stirrer is used at a low speed in high viscosity fluids. With a tangential flow (moving fluid horizontally around the vessel) the Anchor Stirrer will not break/damage sensitive materials and is ideal for the distribution of high mineral content in fluids. Suitable for emulsions, suspensions, gels, colour cosmetics. Can be used with products that contain large particles or beads that you do not want to be broken. With little vertical flow you may use the anchor stirrer at very low speed for higher viscosity surfactant formulations (shampoos, body washes etc) to minimise foaming.
