C8x40mm PTFE Magnetic Stirrer Mixer Bar Laboratory Stir Bar Science Experiment

Introduction to Laboratory Stir Bars & Magnetic Stirring Devices

What is a Laboratory Stir Bar?

A laboratory stir bar, also known as a magnetic stirrer bar, is a small, magnetic rod used in conjunction with a magnetic stirring device to mix liquids in a container. This device is commonly used in scientific experiments and research laboratories.

How Does a Magnetic Stirring Device Work?

A magnetic stirring device consists of a base unit with a rotating magnet that generates a rotating magnetic field. When placed on top of the base unit, the stir bar aligns itself with the rotating magnetic field, causing it to spin and mix the liquid inside the container. This process is both efficient and gentle, making it ideal for a wide range of applications in laboratory settings.
