Description
Magnetic stirring bar octagon, PTFE 8 x 22 mm is a laboratory stirring element designed for reliable mixing in beakers, flasks and other vessels. It features a diameter of 8 mm and a length of 22 mm in an octagonal rod shape that promotes stable rotation and effective agitation on magnetic stirrers. The bar is manufactured from polytetrafluoroethylene (PTFE), providing broad chemical resistance to many laboratory reagents and solvents. This construction keeps the magnetic core protected while allowing smooth, low-friction movement during continuous stirring. Supplied as a pack of 10 pieces from manufacturer Vitlab, the octagon geometry helps maintain consistent performance across a range of speeds and viscosities commonly encountered in routine laboratory work. These stirring bars suit general chemistry, analytical and life-science applications where inert, durable mixing tools are required. The compact 8 x 22 mm dimensions make them suitable for smaller vessels while still delivering thorough mixing action.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about Magnetic stirring-bar, PTFE, OCTAGON, 8 x 22 mm, with pivot ring
What is this article?
Magnetic stirring-bar, PTFE, OCTAGON, 8 x 22 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.
