Overhead stirrers are used for mixing/stirring of liquids. They are useful for both low and very highly viscous liquid. Compared to the hot plate magnetic stirrer, a higher frequency of rotation (up to 3000 rpm) can be generated in an overhead stirrer for stirring larger volumes (up to 200 L) of liquid. Some models can generate both clockwise and anticlockwise rotation. These indispensable features come along with durability and quiet operation. The equipment is explosion proof and comes with a body having a flexible shaft, digital display with timer and the rotation frequency adjuster, a bladed propeller, and a U-shaped stand. An operation manual comes along.
