Why is a magnetic stirrer better?
Magnetic stirrers are silent and provide the possibility of stirring closed systems without the need for isolation, as in the case with mechanical agitators. Because of their size, stir bars can be cleaned and sterilized more easily than other devices such as stirring rods.
Does a magnetic stirrer work?
Magnetic stir bars work well in glass vessels commonly used for chemical reactions, as glass does not appreciably affect a magnetic field. ... For larger volumes or more viscous liquids, some sort of mechanical stirring (e.g., an overhead stirrer) is typically needed.
Do I need a magnetic stirrer?
If you are mixing a low-viscosity liquid in higher volumes, an overhead stirrer is probably the right way to go. However, if your liquid is more viscous and you don't need the extra capacity that overhead stirrers offer, a magnetic stirrer is a better choice since you don't have to worry as much about overheating.Nov 20, 2018
What do you use a magnetic stirrer for?
6.2. 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.
How does a magnetic stir bar 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.Nov 20, 2018
What are the magnetic stirrers called?
What is a magnetic stir bar made of?
Many stir bars are made with ceramic or Alnico magnets. Ceramic magnets are inexpensive and common, but not nearly as strong as a neodymium magnet. They have only about 8-10% of the pull force. Alnico magnets are made from aluminum, nickel and cobalt.
What is digital magnetic stirrer?

What is the function of magnetic stirrer?
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 is a magnetic stirrer called?
Vortex mixer, static mixer. 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.
