You searched for: Magnetic Stirring Bars

Magnetic stirring bars provide effective stirring of samples via magnetic manipulation. Many models feature an octagonal shape with a central integrated pivot ring for optimal turbulence while stirring thanks to a greater surface area. Commonly coated in Teflon to provide chemical inertness; occasionally glass will be the coating for use with most liquid alkali metals and alkali metal solutions in ammonia. Both of these coatings are inert and will not contaminate or react with the reaction solution.

Magnetic stirring bars, PTFE, octagonal, with pivot ring, Spinbar®, SP Bel-Art

Supplier: Bel-Art Products, a Part of SP

PTFE encapsulated octagonal magnetic stirring bars with integral pivot ring are the most commonly used shape. Their interrupted profile provides greater surface area and added turbulence when compared to the smooth surface of cylindrical bars.

Magnetic stirring bars, octagonal, rare earth, Spinbar®, SP Bel-Art

Supplier: Bel-Art Products, a Part of SP

These stirring bars reduce the frequency of spinout in viscous solutions or when stirring at high speeds. The high magnetic field strength of samarium cobalt (Rare Earth) magnets can provide up to three times stronger coupling versus Alnico magnetic stirring bars. Stronger coupling with the drive magnet keeps the stirring bar centered and rotating effectively.
