Description
Magnetic stirring bar 15×6 mm is a cylindrical laboratory stir bar without a centre ring, featuring smooth surfaces for reliable mixing performance. The magnetic core is fully encased in a PTFE coating, combining chemical resistance with low-friction contact against vessel walls. Dimensions are length 15 mm and diameter 6 mm, giving a compact profile suited to small flasks, beakers and reaction vessels. The round bar geometry promotes stable rotation on standard magnetic stirrers. Each pack contains 10 pieces, ready for routine laboratory use. Manufactured by Marienfeld, these PTFE-coated stirring bars are intended for general aqueous and organic media where a plain cylindrical form without a pivot ring is preferred. Smooth exterior surfaces help minimise residue build-up and simplify cleaning between experiments, supporting consistent day-to-day stirring workflows in research, quality control and teaching laboratories.

Questions about Magnetic stirring bars 15x6 mm,
What is this article?
Magnetic stirring bars 15x6 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.
