Description
BOLA triangular magnetic stirring bars with PTFE coating are laboratory stir bars intended for reliable agitation in chemical, analytical and preparative procedures. Each bar contains an Alnico 5 magnetic core fully sheathed in polytetrafluoroethylene (PTFE), offering universal chemical resistance against solvents, acids and bases commonly used in the lab. Approximate dimensions are 35 mm length and 10 mm diameter, with an edge length of 10 mm; the triangular rod form encourages effective turbulence and uniform mixing across a useful range of stirrer speeds. The continuous PTFE coating isolates the magnet from the medium, maintains inert product contact and supports long service life under repeated use. Net weight is 0,005 kg. Provided as a single piece, this BOLA stir bar from manufacturer Bohlender is appropriate for vessels that accommodate a medium-length triangular profile. Material selection, geometry and magnetic core work together to give stable coupling on magnetic stirrers and consistent mixing performance in research and quality-control settings where chemical inertness is essential.

Questions about BOLA Triangular Magnetic Stirring Bars, L 35 mm Ø 10 mm PTFE-coated
What is this article?
BOLA Triangular Magnetic Stirring Bars, L 35 mm Ø 10 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.
