Magnetic stir bar is made from ALNICO, one of the strongest permanent magnets available
The sintered manufacturing process reduces the chance of decoupling (spin outs), which weaker stir bars often suffer from
Encapsulation in PTFE protects both magnet and what it is stirring. Chemically inert and easy to clean
Can withstand 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
