Description
Magnetic stirring bar polygon, PTFE, 2 x 7 mm is a compact laboratory stirring element intended for efficient mixing of small liquid volumes. Manufactured from chemically resistant polytetrafluoroethylene (PTFE), the polygonal special-shape bar measures 2 mm in diameter and 7 mm in length, allowing use in narrow vessels, vials or micro-scale reaction setups. The PTFE encapsulation protects the internal magnet while providing broad chemical compatibility across common solvents and reagents. Supplied in packs of 10 pieces from manufacturer Vitlab, these stirring bars support consistent agitation on standard magnetic stirrers in analytical, research and quality-control laboratories. The polygonal geometry promotes stable rotation and effective vortex formation even at moderate speeds. Ideal for applications requiring gentle yet thorough mixing of limited sample quantities, the bars resist adhesion and are easy to clean between uses. Their small dimensions make them particularly suitable for microchemistry, sample preparation and educational laboratory work where space inside the vessel is restricted.

Questions about Magnetic stirring-bar, PTFE, POLYGON, 2 x 7 mm
What is this article?
Magnetic stirring-bar, PTFE, POLYGON, 2 x 7 mm is the article on this page. Luminix Health distributes Vitlab 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.
