Overhead stirrers
Overhead (mechanical) stirrers drive a stirring rod immersed in the liquid — the solution for stirring larger volumes and high-viscosity liquids that a magnetic stirrer cannot move. The EnviSense range spans compact models, powerful high-torque units (viscosity up to 100,000 cP) and multi-position flocculation testers for jar tests. We match the power, torque and rod type to the viscosity and volume of the sample.
