How does a magnetic stir plate 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.
What is the purpose of a magnetic stir bar?
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 the applications of magnetic stirrer?
The primary use of magnetic stirrer or hot plate with magnetic stirrer is to conduct biological and chemical experiments by mixing two components. It is equally suitable for solids or liquid samples to obtain a consistent liquid mixture. Examples include media for bacterial growth and chemical synthesis.
What is the major part of magnetic stirrer?
A magnetic stirrer consists of a magnetic bar placed within the liquid which provides the stirring action. The stir bar’s motion is driven by another rotating magnet or assembly of electromagnets in the stirrer device, beneath the vessel containing the liquid.
What is hot plate magnetic stirrer?
A hot plate stirrer or a hot plate magnetic stirrer is a laboratory instrument that is typically used to stir and heat the solution simultaneously. This helps the person performing the experiment speed up the reaction and properly dissolve the solute in the solvent.
How do stir bars spin?
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 can I use instead of a magnetic stirrer?
Propeller stirrer for TitraLab® titrators and sample changers. The Propeller stirrer, 70 mm shaft, for AT Titrator (Product # LZE143) can be used in place of the default magnetic stirrer and stir bars on the AT1000 Series Potentiometric Titrators.
Can magnetic stirrers be heated?
