Description
BOLA triangular magnetic stirring bars with PTFE coating are laboratory mixing elements built around an Alnico 5 magnetic core fully enclosed in polytetrafluoroethylene. The PTFE overcoat provides universal chemical resistance, so the bars can be used with a wide range of laboratory reagents while protecting the magnet. Dimensions are approximately 40 mm in length and 14 mm in diameter, with a triangular rod cross-section whose edge length is 15 mm. This three-sided geometry supports effective agitation and stable coupling to the drive magnet during stirring. Net weight is 0,012 kg per piece. Supplied as a single unit, the stirring bar suits everyday mixing in beakers, flasks and other vessels on magnetic stirrers. The chemically inert PTFE surface from manufacturer Bohlender keeps the core isolated from corrosive media, while the triangular profile assists in generating useful turbulence. These BOLA bars meet routine needs in chemical and analytical laboratories where durable, chemically resistant magnetic stirring bars are required for consistent sample preparation and general process work.

Questions about BOLA Triangular Magnetic Stirring Bars, L 40 mm Ø 14 mm PTFE-coated
What is this article?
BOLA Triangular Magnetic Stirring Bars, L 40 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.
