Description
BOLA square magnetic stirring bars measuring 14 x 14 x 45 mm provide a robust bar-shaped option for magnetic mixing in laboratory vessels. Each unit incorporates an Alnico 5 magnetic core completely coated with polytetrafluoroethylene (PTFE), giving universal chemical resistance for use with solvents, acids, bases and other media commonly handled in research and industrial laboratories. The square cross-section promotes strong coupling with the drive magnet and supports effective turbulence during stirring, while the PTFE encapsulation protects both the core and the sample. Offered as a single piece from manufacturer Bohlender, this stirring bar is suited to dissolution studies, reagent preparation, synthesis work-up and general agitation tasks where a durable, chemically inert stir bar is required. Net weight is 0,035 kg. Diameter is specified as 14 mm with a length of 45 mm, matching the square-bar form described for this BOLA model. The combination of Alnico 5 magnetism and full PTFE coverage makes the bar a practical choice for routine and demanding magnetic stirring applications on standard laboratory stirrers.

Questions about BOLA Square Magnetic Stirring Bars, 14 x 14 x 45 mm PTFE-coated
What is this article?
BOLA Square Magnetic Stirring Bars, 14 x 14 x 45 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.
