Description
Magnetic stirring bar, cylindrical, PTFE coated, approx. 15 x 4,5 mm provides efficient, contact-free mixing for laboratory liquids driven by magnetic stirrer plates. Its cylindrical form and full PTFE coating ensure low-friction rotation, broad chemical compatibility and easy cleaning after use with acids, bases or organic solvents. Measuring approximately 15 x 4,5 mm, the bar fits comfortably in medium-small vessels, Erlenmeyer flasks and reaction tubes common in synthetic chemistry, quality control and life-science applications. The inert PTFE layer shields the magnet core from aggressive media and prevents sample contamination. Offered as a single unit, this stirring bar from manufacturer Hecht works seamlessly with conventional magnetic stirring equipment. The balanced cylindrical profile maintains stable centring during operation, delivering uniform agitation and supporting reproducible experimental outcomes. Suitable for routine solution preparation, dissolution studies and gentle mixing of temperature-sensitive samples, the bar combines durability with straightforward handling. Its compact yet slightly longer dimensions offer improved torque transmission compared with shorter variants while remaining fully submersible in typical laboratory volumes.

Questions about Magnetic stirring bars, cylindrical, PTFE coated ca. 15 x 4,5 mm
What is this article?
Magnetic stirring bars, cylindrical, PTFE coated ca. 15 x 4,5 mm is the article on this page. Luminix Health distributes Hecht 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.
