Description
BOLA triangular magnetic stirring bars, length approximately 130 mm and diameter approximately 38 mm, are large-format laboratory stir bars built around an Alnico 5 magnetic core fully encased in PTFE. The triangular rod profile, with an edge length of 44 mm, delivers strong mixing action and stable coupling in larger vessels while helping to control spin-out under demanding stirrer settings. Polytetrafluoroethylene (PTFE) confers universal chemical resistance, allowing use across many common laboratory chemicals without compromising the magnetic core. The coated surface runs smoothly against glass or other vessel materials during extended mixing cycles. Supplied as one piece with a net weight of 0,345 kg, this size from manufacturer Bohlender is intended for higher-volume beakers and reactors where thorough homogenisation is essential. Approximate dimensions of 130 mm length and 38 mm diameter follow the BOLA Dreikant construction, providing robust magnetic drive and efficient turbulence for chemical synthesis, process development and general laboratory stirring applications.

Questions about BOLA Triangular Magnetic Stirring Bars, L 130 mm Ø 38 mm PTFE-coated
What is this article?
BOLA Triangular Magnetic Stirring Bars, L 130 mm Ø 38 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.
