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 does a magnetic stirrer do to water?
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.
Can you autoclave a magnetic stir bar?
Fisherbrand™ Azlon™ Micro Magnetic Stirrer Bars are ideal for small vessels, test tubes and vials. Provides stable stirring action. These PTFE magnetic stir bars are autoclavable and include a pivot ring.
What is the use of a magnetic stirrer?
A magnetic stirrer is an equipment used to create rotating magnetic field. The magnetic stirrer is designed such that there is a small bar magnet and a stand or plate containing the rotating magnet. In general the bar magnet is coated with plastic and plate contains rotating magnet.
What is the working principle of magnetic stirrer?
Magnetic stirrer working principle is repulsive for like charges and attractive for unlike charges . Micro motor drives magnet to generate rotating magnetic field to stir the stirring bar in vessel, making solution conduct completely mixed reaction, stirring speed is adjustable, widely applies to solvent stirring in different viscosity.
How does a magnetic stirrer work?
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. The rotating field may be created either by a rotating magnet or a set of stationary electromagnets, placed beneath the vessel with the liquid.
What is role of magnetic stirrer in pharmaceutical industry?
A magnetic stirrer is primarily used for dissolving, heating, and mixing in pharmaceutical, food and other industries. Specially speaking, there are mainly three uses. Firstly, it can make reactants mix evenly and temperature distribute uniformly. Secondly, it can be used to prevent bumping when heating in a closed vessel.
