Magnetic Stirrer - MRC- Lab

A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (also called 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.

Physics - Stirring Up a Magnetic Field

May 05, 2000 The slow fluid motion of the Earth’s outer core is fast enough to generate a dynamo because of its large size, but researchers need much faster fluid motion to make a dynamo in the lab. Gerbeth and his colleagues from Dresden and the Latvian University in Riga initially applied a small seed field externally while stirring a 2 m 3 container ...

Stirring Viscous Materials Blog

May 14, 2018 The resistance to movement of the stir bar caused by viscous materials prevents the bar from spinning rapidly. This means it won’t be able to provide the turbulence required for thorough mixing. It can also cause the stir bar to become decoupled from the internal magnet, preventing stirring altogether. From left to right: MS-P Series Magnetic ...

How to Choose a Magnetic Stir Bar (Stirring Flea) Blog ...

May 17, 2018 Position the vessel in the middle of the stirrer plate and place the stir bar in the center of the vessel. This will help with coupling and to avoid having the stir bar catch on the side of the vessel. Increase the stirring speed slowly to avoid spinout. As you can see, there are a lot of factors to consider when it comes to choosing the ...

pros and cons of magnetic stirrer. E-Cigarette Forum

Oct 18, 2015 BC Canada. I made a magnetic mixer from videos in youtube it works great if your mixing for personal juice. The computer fan/project box version I made can mix 100mls great. I do think it speeds up steep time a bit but I don't have to shake any juice at all. I mix a couple hours first, I don't add my nic until the mix has steeped its time then ...
