Description
Magnetic stirring bar octagon, PTFE 8 x 64 mm is a precision laboratory stirring element manufactured from chemically inert polytetrafluoroethylene. The octagonal rod geometry improves turbulence and mixing efficiency compared with smooth cylindrical bars, while the PTFE encapsulation protects the internal magnet from aggressive solvents, acids and bases. Diameter is 8 mm and length is 64 mm, providing a balanced size for medium-volume vessels commonly used in synthesis, titration and sample preparation. Supplied in packs of ten pieces, these stirring bars from manufacturer Vitlab are suitable for continuous use on magnetic stirrers and hotplate stirrers across a wide range of chemical applications. The octagonal profile reduces spinning out at higher speeds and ensures reliable coupling with the drive magnet. PTFE construction guarantees broad chemical resistance and easy cleaning, making the bars a durable consumable for routine laboratory workflows that demand reproducible mixing performance without contamination risk.

Questions about Magnetic stirring-bar, PTFE, OCTAGON, 8 x 64 mm, with pivot ring
What is this article?
Magnetic stirring-bar, PTFE, OCTAGON, 8 x 64 mm, with pivot ring 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.
