Description
Magnetic stirring bars with PTFE coating in cylindrical form, L 12 × d 4,5 mm, are compact laboratory stirrers for everyday mixing on magnetic stirrer plates. Each bar combines a magnetic core with a smooth PTFE surface that resists sticking and supports clean handling between runs. The cylindrical geometry suits standard vessels and flasks where a short, slim profile is preferred for controlled agitation. Supplied as a pack of five pieces, the set is practical for stocking multiple workstations or keeping spares ready. Net weight is 0,050 kg per pack. These bars belong to the LBX INSTRUMENTS range from manufacturer Labbox and are intended for general laboratory use. PTFE coating helps maintain chemical resistance during routine aqueous and organic work while the defined length and diameter of 12 mm by 4,5 mm support reproducible stirring behaviour. Ideal for teaching labs, quality-control benches and research setups that rely on consistent magnetic coupling without complex accessories. Dimensions and pack count match the stated specification for straightforward ordering and inventory control.

Questions about Magnetic stirring bar, cylindrical, l 12 x diam. 4,5 mm, 5 pcs
What is this article?
Magnetic stirring bar, cylindrical, l 12 x diam. 4,5 mm, 5 pcs is the article on this page. Luminix Health distributes Labbox 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.
