Are stirrers magnetic?
A magnetic stirrer is a device widely used in laboratories and consists of a rotating magnet or a stationary electromagnet that creates a rotating magnetic field. This device is used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution, for example.
What are magnetic stirrers made of?
Magnetic Stirrers: This vessel, usually made of glass, is placed on the stirring unit’s platform. Underneath the platform, a rotating magnetic field is created by either a rotating magnet or by running electric current through stationary electromagnets.
Can magnetic stirrers be heated?
Depending on the application, you can configure your magnetic stirrer with hot plates to heat your samples as they’re stirred. With the use of heating plates, you can mix a wide variety of samples for different applications.

How do beaker stirrers work?
Magnetic stirrers use a rotating magnetic field to move a stir bar around in liquid samples. The movement of this stir bar mixes the sample thoroughly with rapid movement and agitation. The speed of the magnetic field is controlled by the user, so it can be customized to the specific sample that’s being stirred.
How does a beaker stirrer work?
Magnetic stirrers use a rotating magnetic field to move a stir bar around in liquid samples. The movement of this stir bar mixes the sample thoroughly with rapid movement and agitation. These stirrers should be used with glass or other non-metal beakers to prevent interference with the magnetic field.
How do chemistry stirrers work?
How does it work? A stir bar magnet is placed inside a container, immersed in the fluid. A separate magnet (or magnets) is placed underneath the container, so that it attracts to the stir bar magnet. If the magnets are close enough, the stir bar magnet spins inside the container.
