The Right Choice For Overhead Stirrers

Common in both industrial and academic laboratories, mixing is an important part of many tasks. Deciding which type of stirrer, magnetic or overhead, is best for you depends on the viscosity and scale of the substance you’re stirring. Overhead stirrers – the best fit for high-viscosity applications – are made up of a stirring fixture or panel, a controller, drive shaft, and a drive mechanism or motor. There are a variety of overhead stirrer configurations as well as analog and digital options. To choose the right overhead stirrer and accessories for your lab, it’s always a good idea to get help from your vendor.
