Description
BOLA wing magnetic stirring bars measuring approximately L × W × H 8,0 × 8,0 × 11 mm are PTFE laboratory stirrers engineered for efficient mixing in small-diameter vessels. Each bar incorporates a PTFE-coated Alnico 5 magnetic core together with a tapering stirring wing that is permanently fixed to a cylindrical magnetic stirring bar. Universal chemical resistance of the PTFE coating allows contact with a wide spectrum of laboratory chemicals and solvents while protecting the magnetic element. The geometry is matched to vessels with an internal diameter of 9–10 mm, making the bars suitable for narrow tubes, small flasks and comparable glassware used in research and quality-control settings. The wing profile assists fluid circulation under magnetic drive, and the smooth PTFE surface supports straightforward cleaning and reduced residue carry-over. Supplied as a pack of 3 pieces from manufacturer Bohlender, these stirrers integrate readily with standard magnetic stirrer hotplates. Approximate net weight is 0,001 kg. They provide a durable, chemically inert option for everyday magnetic stirring tasks that require compact wing-type bars in confined reaction vessels.

Questions about BOLA Magnetic Stirring Bars with Blade, LxBxH 8,0 x 8,0 x 11 mm PTFE-coated
What is this article?
BOLA Magnetic Stirring Bars with Blade, LxBxH 8,0 x 8,0 x 11 mm PTFE-coated is the article on this page. Luminix Health distributes Bohlender 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.
