Description
Magnetic stirring bar octagon, PTFE 8 x 13 mm is a compact laboratory stirring element intended for reliable mixing in small vessels and reaction containers. With a diameter of 8 mm and a length of 13 mm, the octagonal rod geometry promotes stable coupling to the drive magnet and reduces the tendency to spin out during operation. The bar is fully encapsulated in polytetrafluoroethylene (PTFE), giving broad chemical resistance toward common laboratory solvents, acids and bases while protecting the internal magnet. These stirring bars from manufacturer Vitlab are supplied as a convenient pack of 10 pieces, making them practical for multi-station work or routine replacement. The octagonal profile improves turbulence compared with smooth cylindrical bars of similar size, supporting efficient dissolution and homogenisation in chemistry, biochemistry and analytical workflows. Compact dimensions suit test tubes, small flasks and vials where space is limited. PTFE construction ensures easy cleaning and long service life under typical magnetic-stirrer conditions. The product belongs to the standard range of magnetic stirring accessories used across research, quality-control and teaching laboratories.

Questions about Magnetic stirring-bar, PTFE, OCTAGON, 8 x 13 mm, with pivot ring
What is this article?
Magnetic stirring-bar, PTFE, OCTAGON, 8 x 13 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.
