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.

• Octagonal shape with pivot ring creates strong turbulence with minimal chattering and friction
• Bars are easy to differentiate as encapsulated in bright green PTFE
• Autoclave safe
