Description
BOLA Triangular Magnetic Stirring Bars, length approximately 20 mm and diameter approximately 8 mm, are compact laboratory stir bars with a three-edged profile for effective mixing in smaller vessels. Each bar incorporates a PTFE-coated Alnico 5 magnetic core and delivers universal chemical resistance thanks to the polytetrafluoroethylene coating, making it suitable for many solvents, acids and bases used in research and analytical laboratories. Edge length is approximately 8 mm, matching the stated diameter for a defined triangular cross-section that can improve turbulence compared with plain cylindrical bars. Pack size is 1 pc, with a net weight of 0,003 kg. These BOLA stirring bars from manufacturer Bohlender are intended for routine magnetic stirring where chemical inertness and a stable triangular geometry support reproducible agitation. The PTFE surface resists attack under typical laboratory conditions, while the Alnico 5 core provides reliable magnetic coupling to standard stirrer drive plates in beakers, flasks and similar containers.

Questions about BOLA Triangular Magnetic Stirring Bars, L 20 mm Ø 8 mm PTFE-coated
What is this article?
BOLA Triangular Magnetic Stirring Bars, L 20 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.
