Description
Magnetic stirring bar, PTFE, 25 x 12 mm, elliptical provides dependable agitation for a wide range of laboratory vessels. Made from polytetrafluoroethylene (PTFE), it offers excellent chemical resistance and a low-friction surface that withstands most common solvents and reagents. The bar measures 25 mm in length by 12 mm in diameter; its ellipsoid shape ensures smooth, centred rotation and effective vortex generation while minimising the risk of decoupling at elevated speeds. An internal magnet fully encapsulated by the PTFE coating transfers torque reliably from magnetic stirrers and remains protected against corrosion. Available in convenient packs of 10 pieces from manufacturer Brand, these stirring bars support everyday mixing, dissolution, sample preparation and reaction work in chemical, biological and pharmaceutical settings. Easy to clean and thermally stable under normal laboratory conditions, they deliver reproducible performance for research, teaching and quality-control applications where consistent, contamination-free stirring is essential.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about Magnetic stirring bar PTFE, 25 x 12 mm, oval
What is this article?
Magnetic stirring bar PTFE, 25 x 12 mm, oval is the article on this page. Luminix Health distributes Brand 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.
