Ancorette magnetiche

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. The heavy-duty magnetic strips is one of the frequently used tools, strong enough to hold the solution. 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, cylindrical, PTFE, Spinbar®, SP Bel-Art

Supplier: Bel-Art Products, a Part of SP

Stirring bars ensure centering and smooth running characteristics via a small removable pivot ring in the center. The pivot ring minimises the contact area of the bar to the vessel, reduces friction and lessens marring of plastic containers.

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

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

Supplier: Bel-Art Products, a Part of SP

PTFE covered samarium cobalt magnet provides strong coupling with drive magnets making it ideal for use with viscous solutions and efficient, high speed stirring. The fluted octagonal shape creates torque transmission rates to the stirred liquid which are two to three fold higher compared to similarly sized standard stirring 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.
