Description
Magnetic stirring bar octagon, PTFE 10 x 51 mm is a laboratory stirring accessory engineered for reliable mixing in beakers, flasks and other vessels. Manufactured from polytetrafluoroethylene (PTFE), the bar offers broad chemical resistance to acids, bases and organic solvents routinely used in research and quality-control settings. With a diameter of 10 mm and a length of 51 mm, the octagonal cross-section promotes strong magnetic coupling and stable rotation while reducing the tendency to spin out at higher speeds. The smooth PTFE surface resists residue build-up and simplifies cleaning between experiments. Supplied as a practical pack of 10 pieces, the set supports laboratories that require multiple stirrers ready for immediate deployment. These octagonal magnetic stirring bars from manufacturer Vitlab are well suited for synthesis, titration, dissolution, sample homogenisation and general preparative work. The defined geometry contributes to reproducible mixing patterns essential for consistent experimental outcomes in chemistry, life-science and materials laboratories, delivering durable everyday performance on standard magnetic stirrer hotplates.

Questions about Magnetic stirring-bar, PTFE, OCTAGON, 10 x 51 mm, with pivot ring
What is this article?
Magnetic stirring-bar, PTFE, OCTAGON, 10 x 51 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.
