Stirrer Bar Pivot Ring Ptfe 40mm

Magnetic cylindrical stirring bars are octagonal with a smooth surface area, with a pivot ring for vessels with slightly uneven bottoms. The pivot ring reduces the contact surface and enables the stirrer to adopt the optimum position. The magnetic cores are encapsulated with high-grade, crack-resistant PTFE (polytetrafluoroethylene) coating. Ideal for large volumes or highly viscous mixtures. Uses include:

• to stir liquids in a sealed container.
