Description
Magnetic stirring bars, octahedral, coloured blue, diameter 8 mm by length 38 mm are laboratory stir bars intended for magnetic stirring applications. Their blue colour enables straightforward sample identification when multiple vessels are handled in parallel. Each bar is finished with a coloured PTFE coating; compared with unpigmented PTFE this coloured layer is less inert and pure, which should be taken into account for sensitive chemistries. Supplied in packs of five from manufacturer Labbox, the bars support efficient multi-sample work in research and quality-control laboratories. The octahedral geometry encourages steady spinning and thorough mixing across a useful range of vessel sizes. Measuring 8 mm in diameter and 38 mm in length, they suit medium flasks and beakers used in everyday preparative and analytical procedures. Pack net weight is 0,100 kg. As LBX INSTRUMENTS magnetic stirring bars, they combine colour coding with a practical mid-length format for organised, reliable stirring in routine laboratory practice.

Questions about Magnetic stirring bar, octahedral, coloured, blue, d 8 x L 38 mm, 5 pcs
What is this article?
Magnetic stirring bar, octahedral, coloured, blue, d 8 x L 38 mm, 5 pcs is the article on this page. Luminix Health distributes Labbox 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.
