Description
Magnetic stirring bar, PTFE, 25 x 10 mm, octagonal, with centre ring offers dependable liquid agitation for everyday laboratory stirring applications. With a length of 25 mm and a diameter of 10 mm, the octagonal geometry and integrated centre ring provide stable spinning behaviour and efficient energy transfer from the magnetic drive. The bar is manufactured from polytetrafluoroethylene (PTFE), giving it excellent chemical inertness toward a broad spectrum of solvents, acids and bases used in research and routine analysis. The centre ring helps keep the bar centred and reduces the risk of decoupling at elevated stirring speeds. Available as a pack of 10 pieces from manufacturer Brand, these magnetic stirring bars are intended for use in beakers, flasks and other vessels on standard magnetic stirrers. The 25 mm × 10 mm dimensions make the bar suitable for medium-volume samples where a slightly larger cross-section improves mixing efficiency. PTFE construction ensures the magnetic core remains protected while the outer surface stays free from contamination, supporting reproducible results in chemistry, biology and pharmaceutical workflows that require consistent homogenisation.

Questions about Magnetic stirring bar PTFE, 25 x 10 mm, octagonal, pivot ring
What is this article?
Magnetic stirring bar PTFE, 25 x 10 mm, octagonal, pivot ring 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.
