What is a Magnetic Stirrer?

At its core, a magnetic stirrer, often called a magnetic mixer, is a laboratory device designed to effortlessly mix liquids. It achieves this by creating a rotating magnetic field, which in turn spins a small, submerged magnetic bar (or "flea") within the liquid. This elegant mechanism allows for silent, contamination-free stirring, making it ideal for sensitive chemical and biological applications where traditional stirring methods might be impractical.

The Science Behind the Stir

The operation is deceptively simple but incredibly effective. A magnetic stir bar is placed directly into the liquid to be mixed. Beneath the container, within the stirrer device itself, a rotating magnet or a series of electromagnets generates the controlled magnetic field. As this field rotates, it compels the stir bar to spin, thoroughly agitating the liquid.

Engineered for Excellence: The Stir Bar

The stir bar itself is a marvel of material science. Typically, these bars are coated with PTFE (Teflon), known for its exceptional chemical inertness. This ensures that the stir bar will not react with or contaminate the often-sensitive mixtures it's stirring. In specific scenarios, such as high-temperature applications or when PTFE is unsuitable, glass-coated stir bars can be used as an alternative, offering another layer of chemical resistance.
