Magnetic stirrer is a laboratory device used to mix liquids efficiently and consistently. It consists of a rotating magnetic field generated by an electric motor beneath the platform, which drives a stir bar (a small magnet coated in inert material) placed inside the liquid. The stir bar spins, creating a vortex and ensuring thorough mixing. Magnetic stirrers are widely used in chemistry, biology, and pharmaceutical labs for tasks such as dissolving solids, homogenizing solutions, or conducting reactions. They are compact, easy to use, and often include heating elements for temperature control. Their non-invasive design minimizes contamination risks, making them ideal for sensitive applications. Magnetic stirrers are essential tools for achieving uniform mixtures in scientific experiments.
