Description
Magnetic stirring bar 10x3 mm is a cylindrical laboratory stir bar designed for efficient liquid mixing on magnetic stirrers. With a length of 10 mm and a diameter of 3 mm, it incorporates a magnetic core coated in polytetrafluoroethylene (PTFE) and presents smooth surfaces without a centre ring. This configuration enables free rotation and is especially practical in narrow vessels, tubes and small flasks where a slender profile is required. The chemically resistant PTFE encapsulation withstands a wide spectrum of laboratory reagents, supporting use in analytical, biochemical and pharmaceutical workflows. Supplied in packs of 10 pieces from manufacturer Marienfeld, the bars deliver consistent agitation and stable vortex formation at typical stirring speeds. The round rod shape and smooth exterior reduce residue build-up and facilitate thorough cleaning between experiments. Combining adequate magnetic coupling with a compact footprint, the 10×3 mm format suits routine sample preparation, titrations and multi-position stirring platforms that demand reliable, inert performance in everyday laboratory environments.

Questions about Magnetic stirring bars 10x3 mm,
What is this article?
Magnetic stirring bars 10x3 mm, is the article on this page. Luminix Health distributes Marienfeld 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.
