Magnetic Stirrers

Magnetic Stirrers & Stirring Bars

Our magnetic stirrers are mechanically, physically and chemically highly resilent. We offer magnetic stirrers by high quality manufacturers. A magnetic stirrer serves to stir liquid in order to adjust concentration differences in media. The liquid in the beaker or Erlenmeyer Flask is put onto the top plate, under which there is a magnet rotating with adjustable speed. This magnet effects on a second magnet, the magnetic stirring bar, inside the vessel. The magnetic stirring bar is mostly sheathed inside synthetic or glass in order to be chemically inert. The reaction of these two magnets leads to moving the liquid. The top plate of a magnetic stirrer mostly has a heating function as well.The magnetic stirrers are perfectly suitable for smooth to intense mixing and heating of low-viscosity fluids. The hot plate stirrer is your first choice for decomposing organic and inorganic substances. Aspects such as safety, convenience and cost savings have been considerably taken into account during the development of the stirrers. This is reflected in various unique product advantages of our lab hot plates.

Magnetic Stirring Bars

The magnetic stirring bar is an important part of the magnetic stirrer. In order to move liquid, there have to be two magnets working together: One beneath the top plate of the magnetic stirrer, and another one – the magnetic stirring bar – inside the liquid to stir. In order to be chemically inert, the magnetic stirring bar is sheathed in synthetic or glass. The magnet beneath the top plate effects on the magnetic stirring bar inside the liquid which is stirred through the reaction of the two magnets. The top plate of the magnetic stirrers mostly also has a heating function. The movements of the stirring liquid depend on the magnetic stirring bar’s form. There are, for instance, crescent-shaped, anchor-shaped and propeller-shaped magnetic stirring bars. Yet, we also offer turbine stirrers.
