Description
Magnetic stirring bars with PTFE coating, cylindrical, L 12 × d 4,5 mm, provide a bulk pack of thirty pieces for laboratories that consume stirrers regularly. Each bar features a PTFE-coated cylindrical body sized for general magnetic stirring in beakers, flasks and similar vessels. The short 12 mm length and 4,5 mm diameter deliver a slim profile that couples reliably to standard magnetic stirrers while remaining easy to retrieve with a stirring-bar retriever. PTFE coating supports chemical resistance and a low-adhesion surface for routine cleaning between experiments. This thirty-piece pack from manufacturer Labbox suits shared instrument rooms, teaching courses and high-throughput benches where multiple identical bars are needed at once. Net weight is 0,010 kg. The items are part of the LBX INSTRUMENTS line and are described for general use. Consistent geometry across the pack helps maintain comparable mixing performance from station to station, simplifying method transfer and everyday laboratory organisation without specialised accessories.

Questions about Magnetic stirring bar, cylindrical, l 12 x diam. 4,5 mm, 30 pcs
What is this article?
Magnetic stirring bar, cylindrical, l 12 x diam. 4,5 mm, 30 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.
