Description
BOLA cylindrical magnetic stirring bars measuring approximately 8 mm in length and 3 mm in diameter are standard laboratory stir bars with a PTFE-coated Alnico 5 magnetic core. The round rod form provides stable spinning behaviour and efficient mixing performance in typical laboratory vessels. Polytetrafluoroethylene (PTFE) forms the protective overcoat and confers universal chemical resistance, allowing use with a wide variety of reagents and solvents while safeguarding the magnetic core. The Alnico 5 magnet ensures strong, reliable coupling to conventional magnetic stirrers. Offered as 1 pc with a net weight of 0,001 kg, this stirring bar from manufacturer Bohlender belongs to the BOLA standard cylindrical series. Approximate dimensions of 8 mm length and 3 mm diameter make it suitable for general mixing duties in research and analytical laboratories that require an inert contact surface. The PTFE coating supports smooth rotation and helps reduce the risk of medium contamination. Country of origin is Great Britain. These BOLA bars combine chemical inertness with consistent cylindrical geometry for everyday laboratory stirring applications.

Questions about BOLA Cylindrical Magnetic Stirring Bars, L 8 mm Ø 3 mm PTFE-coated
What is this article?
BOLA Cylindrical Magnetic Stirring Bars, L 8 mm Ø 3 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.
