What is the principle of magnetic stirrer?

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.

Besides, how do I choose a magnetic stirrer?

The length of the bar should be about equal to the magnet size to avoid spinout. Spinout occurs when the bar loses its coupling with the internal magnet of the stirrer and the bar stops spinning altogether. Stir bars significantly longer than the internal magnet might reduce the max speed the bar may be spun.

Also question is, how do you make a magnetic stirrer?

Thereof, how do you remove a magnetic stirrer?

Thanks for the suggestions!

  1. Go to your nearest giant electromagnet (an NMR or MRI should do the trick)
  2. Place sample jar near machine.
  3. Stand well back.
  4. Turn on magnet, allowing the bar to be gently removed and placed on the floor.

How do you use a magnetic stirrer?

How does a magnetic stir bar 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.

How many types of stirrers are there?

There are two types of Agitators commonly used, 1. Mechanical Agitators, 2. Electronically Controlled Agitators, I’ll demonstrate commonly used Mechanical Agitators.

What are the types of magnetic stirrer?

Types of a Magnetic Stirrer:

  • Magnetic Mini Stirrer: …
  • Magnetic Stirrer with Timer: …
  • Heavy-Duty Magnetic Stirrer: …

  • Air Operated Turbine Magnetic Stirrer:

What is magnetic stirrer in microbiology?

With the use of a magnetic field, a magnetic stirrer rotates a stir bar. The rod-shaped magnet is placed in a beaker or bottle containing liquids. By rotating the stir bar, the liquid is properly mixed. A magnetic stirrer can, among other things, be used to prepare medium to culture microbes.

What is the use 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.
