Magnetic stir bars work well in glass vessels commonly used for chemical reactions, as glass does not appreciably affect a magnetic field. The limited size of the bar means that magnetic stirrers can only be used for relatively small experiments, of 4 litres or less.
In this way, can magnetic stirrers be heated?
Depending on the application, you can configure your magnetic stirrer with hot plates to heat your samples as they’re stirred. With the use of heating plates, you can mix a wide variety of samples for different applications.
Consequently, 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.
How do you make a magnetic stirrer hot plate?
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.
The plate surface temperature can reach over 250°C when the knob is turned to maximum power. WARNING: Do not use the unit for more than 4 hours on maximum heat. Do not use the unit for more than 8 hours heating continuously. If the unit malfunctions, let it cool completely, then begin operation again.
The hotplate stirrer (or hot plate stirrer or hot plate magnetic stirrer) is used for mixing and heating aqueous solutions for a great variety of chemical reactions such as synthesis.

A magnetic stirrer is a device used to create a rotating magnetic field. … The main function of a stirrer is to agitate the liquid for speeding up the reactions or improving mixtures. A magnetic stirrer is often used with hot plates.
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.
