Description
BOLA Colour magnetic stirring bars in red are cylindrical PTFE laboratory stirrers intended for dependable mixing of liquids and suspensions. Each unit incorporates a dye-coated Alnico 5 magnetic core fully encapsulated in polytetrafluoroethylene, delivering universal chemical resistance against aggressive media commonly encountered in research and quality-control workflows. Approximate dimensions are 13 mm length and 8 mm diameter, with a round bar profile and an integrated centre ring that stabilises rotation and limits contact wear on glass or plastic vessel floors. The vivid red finish enables rapid visual differentiation when multiple coloured bars are deployed side by side. Packaged as 10 pieces, the bars from manufacturer Bohlender are well suited to everyday magnetic stirring tasks such as dissolution, homogenisation and temperature-controlled sample preparation. PTFE construction ensures the magnetic core remains protected while the centre-ring design supports smooth, low-friction spinning across a broad speed range. Their compact size and low net weight of about 0,002 kg make them practical for small vessels and multi-position stirrers alike.

Questions about BOLA Colour Magnetic Stirring Bars, RED L. 12.5 mm Ø 8 mm PTFE-coated, colour: r
What is this article?
BOLA Colour Magnetic Stirring Bars, RED L. 12.5 mm Ø 8 mm PTFE-coated, colour: r 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.
