Magnetic Stirrers

Magnetic stirrers are benchtop lab instruments used to mix and agitate solutions, but using a rotating magnetic field which causes a stirrer bar to rotate. They consist of a small magnetic stir bar, often made of Teflon or glass, which is placed inside a container of liquid. The stir bar is then rotated by a magnetic field generated by the magnetic stirrer. They are typically made of a magnetic plate with a variable speed control that allows the user to adjust the speed of the magnetic field and thus the rotation of the stir bar. These laboratory stirrers are used in a wide range of applications, including sample preparation, biochemical assays, microbiology, and cell culture. They are particularly useful for applications that require gentle mixing or agitation, as the magnetic stir bar rotates the liquid without introducing excessive shear or turbulence. In addition to their use in mixing solutions, magnetic stirrers are also often used for temperature control. Many magnetic stirrers are equipped with a heating element that allows the user to control the temperature of the solution being stirred. This can be particularly useful in applications that require temperature-sensitive reactions or for maintaining constant temperature conditions during incubation or culturing.
