Description
Magnetic stirring bar, PTFE, 25 x 8 mm, triangular is a laboratory mixing element engineered for reliable agitation of liquids on magnetic stirrers. Measuring 25 mm in length and 8 mm in diameter, the bar is fully encapsulated in polytetrafluoroethylene (PTFE) and features a triangular cross-section that generates additional turbulence for thorough homogenisation. The three-edged profile improves mixing efficiency in beakers, flasks and reaction vessels compared with simple cylindrical designs, making it suitable for chemistry, biology and analytical workflows. Supplied in packs of 10 pieces from manufacturer Brand, these stirring bars combine chemical inertness with low-friction performance, allowing continuous use with aqueous and organic media. The compact PTFE construction protects the internal magnet while resisting aggressive solvents and elevated temperatures common in laboratory environments. Lightweight at a net weight of 0,03 kg, the bars integrate easily into routine sample preparation, titration and dissolution procedures without adding bulk. Their durable triangular geometry supports consistent rotation and reproducible results across a variety of vessel sizes and stirring speeds.

Questions about Magnetic stirring bar PTFE, 25 x 8 mm, triangular
What is this article?
Magnetic stirring bar PTFE, 25 x 8 mm, triangular is the article on this page. Luminix Health distributes Brand 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.
