Description
Magnetic stirring bar polygon, PTFE, 6 x 30 mm is a specialised laboratory stirring element designed for efficient mixing of liquids in beakers and flasks. Measuring 6 mm in diameter and 30 mm in length, the polygon-shaped bar is fully encapsulated in polytetrafluoroethylene (PTFE), providing excellent chemical resistance against aggressive solvents, acids and bases commonly encountered in analytical and synthetic work. The special polygonal form improves turbulence and mixing performance compared with conventional cylindrical bars, ensuring thorough homogenisation even at moderate speeds. Supplied in packs of 10 pieces, these stirring bars from manufacturer Vitlab are suitable for use with standard magnetic stirrers and hotplate stirrers in research, quality-control and educational laboratories. The inert PTFE coating prevents sample contamination and allows repeated autoclaving or chemical cleaning without degradation. Compact dimensions make the bars ideal for small-volume vessels while the robust construction guarantees long service life under continuous operation. Ideal for routine sample preparation, titrations and reaction monitoring where reliable, contamination-free stirring is essential.

Questions about Magnetic stirring-bar, PTFE, POLYGON, 6 x 30 mm
What is this article?
Magnetic stirring-bar, PTFE, POLYGON, 6 x 30 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.
