Those mixing granular slurries know that magnetic stirring bars can and do often wear down quicker than preferred. Manufactured with different processes and materials, new SpinfinityŽ magnetic stirring bars have a hard plastic covering that delivers 2.5 to 3 times the wear resistance of PTFE coated magnetic stirring bars under conditions known to cause material breakdown.
The SpinfinityŽ magnetic stirring bar is an octagon shape with a molded-in pivot ring. This shape provides greater surface area than a rounded bar of similar size and an interrupted profile which provides added turbulence for efficient stirring. The pivot ring reduces friction and chattering. In the lab, they can quickly be identified from other magnetic stirring bars by their distinctive purple coating.
