Description
Magnetic stirring bars with PTFE coating, oval form, measuring 50 x 20 mm, are laboratory accessories for mixing liquids on magnetic stirrers. With a PTFE coating they are particularly suitable for round-bottom flasks, where the oval profile supports thorough agitation along curved vessel walls. This pack contains 30 pieces and has a net weight of 1,038 kg, giving laboratories a generous stock quantity for continuous daily use. Produced by Labbox within the LBX INSTRUMENTS range, the bars pair a PTFE surface with an oval geometry appropriate for flasks and similar glassware. Magnetic stirring bars of this format are employed for dissolving solids, combining reagents and keeping suspensions homogeneous during sample preparation, synthesis support and general wet-chemistry workflows. Dimensions of 50 mm by 20 mm offer a practical size for medium-scale vessels. The PTFE coating supports chemical compatibility with many common laboratory media and helps reduce mechanical stress on glass surfaces. These oval magnetic stirring bars provide a reliable consumable option for research, quality-control and teaching environments that depend on consistent magnetic stirring performance.

Questions about Magnetic stirring bar, oval, l 50 x diam. 20 mm, 30 pcs
What is this article?
Magnetic stirring bar, oval, l 50 x diam. 20 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.
