A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (or flea) immersed in a liquid to spin very quickly, thus stirring it.

What Is a Magnetic Stir Bar? Magnetic stir bars are stirrers or stirring hotplates used with magnets to mix a liquid or solution by creating a vortex. A number of factors affect magnetic stir bar efficiency and effectiveness, including its size, shape, and material.

These neodymium stir bar magnets consist of a powerful neodymium magnet encased in a molded layer of PTFE. The shape includes a molded ridge, or pivot ring to make rotation easier and smoother. Stronger than comparable Alnico magnets, these neodymium stir bars do not tend to demagnetize over time.

The ALNICO magnetic stir bar withstands temperatures up to 250°C, making them suitable for use with both unheated and heated stirrers. Low friction octagon shape with a center pivot ring helps create a strong mixing vortex, even with more viscous solutions. Features and Benefits.

Spinbar ® magnetic stir bar is used in conjunction with a magnetic stirring plate for uniform, consistent, and thorough mixing of chemical solutions.; Alnico magnet encapsulated in durable and inert FDA grade polytetrafluoroethylene (PTFE) low friction coating. Multi-faceted-shaped bars provide a greater surface area and added turbulence for more vigorous, thorough mixing.
