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.
Similarly, how do stir plates work?
A separate magnet (or magnets) is placed underneath the container, so that it attracts to the stir bar magnet. The lower magnet is usually attached to a motor that spins it. If the magnets are close enough, the stir bar magnet spins inside the container.

What is a hot plate stirrer used for?
The hotplate stirrer (or hot plate stirrer or hot plate magnetic stirrer) is used for mixing and heating aqueous solutions for a great variety of chemical reactions such as synthesis. VELP hotplate stirrers are available in various models and combinations in both analog and digital configurations.
What is a scientific stirrer called?
A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (or flea) immersed in a liquid to spin very quickly, thus stirring it.
What is immersed in the liquid to provide the stirring action?
The main function of a stirrer is to agitate the liquid for speeding up the reactions or improving mixtures. A magnetic stirrer is often used with hot plates. The stir bar is the magnetic bar which is immersed in the liquid to provide the stirring action.
What is magnetic stirrer principle?
Magnetic stirrers use a rotating magnetic field to move a stir bar around in liquid samples, and some are coupled with stirring hot plate. The movement of this stir bar mixes the samples thoroughly with rapid movement and agitation.
What is mechanical stirring?
In mechanical stirring desulfurization processes, a stirrer made of a refractory material is immersed and rotated in the hot metal. From: Treatise on Process Metallurgy: Industrial Processes, 2014.
What is stirrer flask?
These flasks are stirred tank bioreactors, in which impeller mixing maintains the cells in suspension and the fluid movement helps in mass transport of nutrients and wastes.
What is stirrer motor?
The primary function of the stirrer shaft is to transmit torque from the stirrer motor to the impeller. Torque is the tendency of a force to cause an object to rotate. The magnitude of the torque around the shaft axis is related to the power required for operation of the impeller.
What is the price of magnetic stirrer?
