Description
BOLA triangular magnetic stirring bars with PTFE coating are compact laboratory stir bars for controlled mixing in chemical, analytical and preparative work. Each unit incorporates an Alnico 5 magnetic core fully encapsulated in polytetrafluoroethylene (PTFE), giving universal chemical resistance toward common laboratory solvents, acids and bases. Approximate dimensions are 25 mm length and 8 mm diameter, with an edge length of 8 mm; the triangular rod profile promotes effective turbulence and thorough homogenisation even at moderate stirrer speeds. The continuous PTFE overcoat isolates the magnet from the process medium, maintains inert product contact and supports repeated use on standard magnetic stirrers. Net weight is 0,004 kg. Offered as a single piece, this BOLA stir bar from manufacturer Bohlender is well suited to small vessels and routine laboratory setups where a short triangular geometry is preferred. Material, geometry and magnetic core together provide stable coupling and reliable mixing performance across typical research and quality-control applications without introducing reactive surfaces into the mixture.

Questions about BOLA Triangular Magnetic Stirring Bars, L 25 mm Ø 8 mm PTFE-coated
What is this article?
BOLA Triangular Magnetic Stirring Bars, L 25 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.
