Description
BOLA triangular magnetic stirring bars with PTFE coating are compact laboratory stirrers for controlled mixing in small vessels. Each bar measures approximately 12 mm in length and 8 mm in diameter, with an edge length of 6 mm, giving a three-sided profile that promotes stable rotation and efficient turbulence at low to moderate speeds. The magnetic core is Alnico 5 and is fully encapsulated in polytetrafluoroethylene (PTFE), providing universal chemical resistance against aggressive solvents, acids and bases commonly used in analytical and preparative work. The PTFE surface remains inert, low-friction and easy to clean, supporting reproducible stirring without sample contamination. Supplied as a pack of three pieces from manufacturer Bohlender, these triangular bars suit everyday magnetic stirring tasks on hotplate stirrers where a short, robust geometry is preferred. Net weight is 0,001 kg per unit. Their compact triangular form helps maintain centred motion in narrow flasks, tubes and small reaction vessels while the durable PTFE overcoat protects the magnet during repeated autoclave-free laboratory handling and chemical exposure.

Questions about BOLA Triangular Magnetic Stirring Bars, L 12 mm Ø 8 mm PTFE-coated
What is this article?
BOLA Triangular Magnetic Stirring Bars, L 12 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.
