Description
BOLA cylindrical magnetic stirring bars with approximate dimensions of 30 mm length and 7 mm diameter are versatile standard stir bars intended for general laboratory agitation. The Alnico 5 magnetic core is fully sheathed in polytetrafluoroethylene (PTFE), furnishing universal chemical resistance that withstands a wide spectrum of solvents, acids and bases used in research and process laboratories. Their cylindrical round-rod profile promotes smooth, continuous rotation on magnetic stirrers and hotplate stirrers, supporting uniform mixing in beakers, flasks and other vessels. A net weight of 0,005 kg keeps the bars easy to manipulate while still providing strong magnetic coupling. These stirring bars from manufacturer Bohlender feature an inert PTFE exterior that resists adhesion, simplifies cleaning and protects the magnet from corrosive media. They are well suited to sample preparation, synthesis assistance, teaching labs and quality-control routines that demand dependable stirring performance day after day. Supplied individually as one piece, each bar is immediately ready for use wherever broad chemical compatibility and stable magnetic agitation are required in everyday laboratory practice.

Questions about BOLA Cylindrical Magnetic Stirring Bars, L 30 mm Ø 7 mm PTFE-coated
What is this article?
BOLA Cylindrical Magnetic Stirring Bars, L 30 mm Ø 7 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.
