350C 2000RPM 1-Gallon PID Magnetic Stirrer With 7" Heated Plate
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 quickly, thus stirring it. A rotating magnet or a set of stationary electromagnets placed beneath the vessel with the liquid may create a rotating field. Since glass does not affect a magnetic field appreciably (it is transparent to magnetism), and most chemical reactions take place in glass vessels (i.e., see beaker (glassware) or laboratory flasks), magnetic stir bars work well in glass vessels. On the other hand, the limited size of the bar means that magnetic stirrers can only be used for relatively small experiments. They also have difficulty dealing with viscous liquids or thick suspensions. Mechanical stirring is typically needed for larger volumes or more viscous fluids.
Magnetic stirrers are often used in chemistry and biology. They are preferred over gear-driven motorized stirrers because they are quieter, more efficient, and have no moving external parts to break or wear out (other than the simple bar magnet itself). Because of its small size, a stirring bar is more easily cleaned and sterilized than other stirring devices. They do not require lubricants, which could contaminate the reaction vessel and the product. They can be used inside hermetically closed vessels or systems without complicated rotary seals. Magnetic stirrers may also include a hot plate or other liquid heating methods.
