Description
BOLA Colour magnetic stirring bars in blue are cylindrical PTFE laboratory stirrers with a dye-coated Alnico 5 magnetic core and an integral centre ring for stable, centred rotation. Each bar measures approximately 50 mm in length and 8 mm in diameter, providing a longer format for larger vessels and higher liquid volumes. The polytetrafluoroethylene encapsulation offers universal chemical resistance, making the bars suitable for a wide spectrum of aqueous and organic media in research, synthesis and quality-control environments. Blue colour coding supports rapid visual selection when multiple stirrers are deployed. Packaged in units of 3 pieces, with a net weight of about 0,011 kg per bar, they suit applications that need a longer stirring element without excess inventory. These BOLA Colour bars from manufacturer Bohlender combine PTFE inertness with a strong magnetic core in a round rod shape that maintains dependable magnetic coupling. They support dissolution, homogenisation and general mixing where chemical compatibility, reliable motion and clear colour-and-size identification are important.

Questions about BOLA Colour Magnetic Stirring Bars, BLUE L. 50 mm Ø 8 mm PTFE-coated, colour: bl
What is this article?
BOLA Colour Magnetic Stirring Bars, BLUE L. 50 mm Ø 8 mm PTFE-coated, colour: bl 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.
