Description
Magnetic stirring bars with PTFE coating, oval form, measuring L 50 x d 20 mm, are laboratory accessories intended for controlled mixing on magnetic stirrers. The PTFE coating and oval geometry make them particularly suitable for round-bottom flasks, supporting stable agitation along curved glass walls. Supplied as a pack of 5 pieces with a net weight of 0,050 kg, they offer a compact quantity for focused experimental work or smaller laboratory setups. These bars from manufacturer Labbox belong to the LBX INSTRUMENTS product type and combine a PTFE surface with dimensions suited to medium-volume flasks and comparable vessels. Oval magnetic stirring bars of this size are applied when dissolving solids, blending reagents or maintaining homogeneous suspensions during sample preparation and routine wet-chemistry procedures. A length of 50 mm and diameter of 20 mm provide a balanced profile for effective stirring performance. The PTFE coating aids chemical compatibility with many common laboratory media and helps limit mechanical wear on glassware. This five-piece pack is a practical choice for research, teaching and quality-control laboratories that need reliable PTFE-coated oval stir bars.

Questions about Magnetic stirring bar, oval, l 50 x diam. 20 mm, 5 pcs
What is this article?
Magnetic stirring bar, oval, l 50 x diam. 20 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.
