Description
BOLA cylindrical magnetic stirring bars with PTFE coating are standard laboratory stir bars intended for reliable agitation across diverse chemical media. An Alnico 5 magnetic core is fully enclosed in polytetrafluoroethylene, combining strong magnetic coupling with universal chemical resistance and low risk of sample contamination. Approximate dimensions are 45 mm length and 8 mm diameter in a round rod form that runs smoothly on magnetic stirrers and hotplate stirrers. The PTFE overcoat shields the core from corrosive reagents while remaining inert toward many solvents, acids and bases encountered in research, synthesis and quality control. Packs contain 10 pieces, each with a net weight of about 0,008 kg, providing a convenient quantity for everyday laboratory use. These BOLA stirrers from manufacturer Bohlender fit vessels appropriate to their size and deliver stable cylindrical rotation whenever consistent mixing and broad chemical compatibility are required in analytical or preparative workflows.

Questions about BOLA Cylindrical Magnetic Stirring Bars, L 45 mm Ø 8 mm PTFE-coated
What is this article?
BOLA Cylindrical Magnetic Stirring Bars, L 45 mm Ø 8 mm PTFE-coated is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Magnetic stirring bars, inside Stirring, shaking & mixing, in Lab instruments.
A magnetic stirring bar is the magnet coated in PTFE that spins inside a vessel, driven by a stirrer underneath. Length and shape, plain, oval or cross, have to suit the flask. A bar left against a dry glass wall will grind it.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
