Description
Magnetic stirring bar polygon, PTFE, 27 x 159 mm is a special-shape laboratory stir bar engineered for efficient mixing in a wide range of vessels. Manufactured from chemically resistant polytetrafluoroethylene (PTFE), the polygonal profile promotes strong vortex formation and stable rotation even at higher speeds. Measuring 27 mm in diameter and 159 mm in length, this bar suits larger flasks and beakers commonly used in synthesis, sample preparation and general laboratory stirring applications. Supplied in packs of 10 pieces, the bars offer reliable performance across aqueous and many organic media thanks to the inert PTFE encapsulation. The special polygonal geometry from manufacturer Vitlab reduces spinning out and improves mixing homogeneity compared with simple cylindrical designs. Suitable for use with standard magnetic stirrers, these PTFE stirring bars provide durable, contamination-free agitation for research, quality-control and educational laboratories requiring consistent results.

Questions about Magnetic stirring-bar, PTFE, POLYGON, 27 x 159 mm
What is this article?
Magnetic stirring-bar, PTFE, POLYGON, 27 x 159 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.
