Description
Magnetic stirring bars with PTFE coating, oval profile, L 20 x d 10 mm, are compact laboratory stir elements for magnetic stirrers. The oval geometry is particularly suitable for round-bottom flasks, where the curved outline helps the bar track the vessel base and maintain steady rotation during mixing. A continuous PTFE coating encloses the magnetic core, giving a chemically resistant outer surface for routine contact with common laboratory solvents and aqueous media. Each unit pack contains 5 pc(s) and has a net weight of 0,050 kg, so several stations can be equipped from one order without excess bulk. These bars are offered by manufacturer Labbox in the LBX INSTRUMENTS line and support everyday agitation in synthesis, sample preparation, teaching labs, and quality-control workflows. Length 20 mm and diameter 10 mm suit small to medium flasks and similar vessels on standard magnetic stirrers. The PTFE surface is easy to rinse between runs and helps protect the internal magnet under normal bench conditions. Compact packaging supports tidy storage beside hotplate stirrers and reaction setups that rely on PTFE-coated oval stir bars for reliable liquid mixing.

Questions about Magnetic stirring bar, oval, l 20 x diam. 10 mm, 5 pcs
What is this article?
Magnetic stirring bar, oval, l 20 x diam. 10 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.
