Cylindrical stir bars are laboratory devices used for stirring and mixing liquids in a container or vessel. They are made of a magnetic material such as PTFE (polytetrafluoroethylene), glass, or stainless steel, and are designed to work with magnetic stirrers.
The cylindrical shape of the stir bars provides good mixing performance and helps to prevent vortex formation, which can introduce air bubbles and affect the quality of the sample. The cylindrical shape also minimizes friction with the side of the container, reducing the risk of damage to the stir bar and the vessel.
