Komet magnetic stirring bars made from SmCo (Samarium Cobalt) have a PTFE coating which means they can be sterilised. Particularly recommended for high speed stirring, liquids with a high viscosity and stirring in vessels where there is a large distance between stirrer and stirring bar, such as measuring cyliners.

• Magnetic power two to three times higher than that of conventional bars
• Magnetic properties remain for many years
