Description

A stirrer is a laboratory instrument used to mix or stir liquids or solutions in various vessels such as beakers, flasks, or test tubes. It typically consists of a motor-driven magnetic or mechanical stirring mechanism that agitates the liquid when placed in the vessel. Stirrers are available in different designs, including magnetic stirrers that use a rotating magnetic field to spin a magnetic stir bar inside the vessel and overhead stirrers that feature a motor-driven shaft and paddle or propeller for stirring. Stirrers are essential tools in chemistry, biology, and pharmaceutical laboratories for tasks such as solution preparation, chemical reactions, and sample mixing, offering efficient and homogeneous mixing of liquids.
