Description
BOLA cylindrical magnetic stirring bars with PTFE coating are standard laboratory stir bars featuring an Alnico 5 magnetic core completely enclosed in polytetrafluoroethylene. The PTFE jacket provides universal chemical resistance, allowing safe use with many acids, bases and solvents while isolating the magnet from the working medium. Approximate dimensions are 155 mm length and 27 mm diameter in a robust round-rod cylindrical shape intended for larger vessels and applications that benefit from greater bar length and magnetic mass. Net weight is 0,3 kg, supporting strong coupling and steady mixing performance on magnetic stirrers and hotplate stirrers. The cylindrical geometry encourages smooth tumbling and dependable vortex formation during routine laboratory stirring, dissolution and process work. These stirring bars from manufacturer Bohlender come as single pieces ready for immediate deployment. With an inert PTFE contact surface and a sealed Alnico 5 core, they serve as durable, chemically resistant consumables for research, quality-control and production laboratories needing clearly specified cylindrical stir bars.

Questions about BOLA Cylindrical Magnetic Stirring Bars, L 155 mm Ø 27 mm PTFE-coated
What is this article?
BOLA Cylindrical Magnetic Stirring Bars, L 155 mm Ø 27 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.
