Magnetic stirrers are essential tools in laboratories, used for mixing liquids quickly and efficiently. These stirrers work by creating a rotating magnetic field, causing a stir bar to spin within the liquid, ensuring even mixing. They are commonly used in chemical, biological, and pharmaceutical labs. Modern magnetic stirrers, like the M 221, come with advanced features such as digital displays, external temperature control sensors, and variable stirring speeds, which allow precise control of the mixing process. They are highly reliable, require minimal maintenance, and are suitable for long-term continuous operation.
