Description
BOLA cylindrical magnetic stirring bars, length approximately 6 mm and diameter approximately 3 mm, are standard laboratory stir bars for dependable mixing in small to medium vessels. Each bar incorporates an Alnico 5 magnetic core fully enclosed in a polytetrafluoroethylene (PTFE) coating that provides universal chemical resistance against a wide spectrum of solvents and reagents. The round cylindrical geometry ensures smooth rotation on magnetic stirrers and stable stirring performance in research and analytical workflows. Pack size is 1 pc, convenient for targeted small-volume and general laboratory applications. With a net weight of 0,001 kg, the bar is lightweight yet suitable for routine laboratory conditions. The PTFE overcoat safeguards the magnetic core while remaining inert to aggressive chemicals, making these bars appropriate for chemistry, life-science and quality-control laboratories requiring chemically resistant stirring elements. Approximate dimensions of 6 mm length and 3 mm diameter align with the compact BOLA cylindrical range from manufacturer Bohlender for everyday magnetic stirring tasks in glassware and reaction vessels.

Questions about BOLA Cylindrical Magnetic Stirring Bars, L 6 mm Ø 3 mm PTFE-coated
What is this article?
BOLA Cylindrical Magnetic Stirring Bars, L 6 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.
