To use the magnetic stirrer:
Turn on the magnetic stirrer by flipping the power switch on (–), then rotating the left knob in a clockwise direction. 3. The farther you rotate the knob, the faster it will spin to stir your solution. You can control the stirring speed between about 120 and 1400 rpm.
Hereof, how do you make a cheap portable magnetic stirrer?
The stir bar is made of two magnets embedded in the moldable plastic. Simply place the plastic in a container of hot water until it turns clear. Place two magnets (polarities opposite facing) onto the plastic and surround with more of the moldable plastic until the magnets are covered.
In respect to this, how do you make a magnetic stir bar?
How do you sterilize a magnetic stirrer?
How do you use a magnetic stirrer with a hot plate?
How does a 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 strong are neodymium magnets?
How Strong Are Neodymium Magnets? Very strong. They will amaze you! A 2-gram (0.07 ounce) neodymium magnet that measures 8 millimeters (0.315 inches) in diameter and 5 millimeters (0.197 inches) long generates a force of over 1700 grams (3.75 pounds).
Is magnetic stirrer good?
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.
What does a magnetic stirrer do to water?
Unsourced material may be challenged and removed. 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.
