Description
BOLA triangular magnetic stirring bars with PTFE coating are laboratory stir bars engineered for efficient mixing in chemical and analytical environments. A magnetic core of Alnico 5 is completely enclosed in polytetrafluoroethylene (PTFE), providing universal chemical resistance to aggressive media routinely handled in the laboratory. Approximate dimensions are 25 mm length and 14 mm diameter, with an edge length of 15 mm; the triangular cross-section generates strong turbulence and supports thorough blending at practical stirrer speeds. The seamless PTFE jacket protects the magnet, ensures inert contact with the process fluid and withstands repeated cleaning and reuse. Net weight is 0,007 kg. Supplied as one piece, this BOLA stir bar from manufacturer Bohlender fits vessels that benefit from a short, relatively wide triangular profile. The combination of PTFE encapsulation, defined geometry and Alnico 5 core delivers dependable magnetic coupling and consistent mixing behaviour for research, development and quality-control workflows requiring chemically inert stirring elements.

Questions about BOLA Triangular Magnetic Stirring Bars, L 25 mm Ø 14 mm PTFE-coated
What is this article?
BOLA Triangular Magnetic Stirring Bars, L 25 mm Ø 14 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.
