Magnetic stirrer is a laboratory instrument used to mix liquids or solutions by stirring them continuously using a rotating magnetic field. It consists of a small magnetic bar or stir bar that is placed inside the liquid to be stirred and a magnetic field generator, usually a small motor, that rotates the magnetic bar at a controlled speed. The magnetic bar is usually coated with a non-reactive material such as PTFE (polytetrafluoroethylene) to prevent it from reacting with the liquid or solution being stirred. Magnetic stirrers are widely used in chemistry, biology, and other scientific fields for various applications such as mixing reagents, dissolving solids, and preparing samples for analysis. They are preferred over conventional mechanical stirrers as they are more efficient, do not cause contamination, and are easier to clean.
