Description
Oval magnetic stirring bar 15 x 30 mm is an ellipsoid laboratory stir bar intended for use in round-bottom flasks. It features an outer diameter of 15 mm and a length of 30 mm, giving a compact profile that follows the curved base of typical reaction vessels and supports steady magnetic coupling during mixing. The bar is fully encapsulated in polytetrafluoroethylene (PTFE), a chemically inert polymer that resists attack by many common laboratory reagents and presents a smooth, low-adhesion surface for easy cleaning. Pack size is 10 pc(s), making the item practical for stocking multiple workstations or parallel setups. Net weight is 0,014 kg. The ellipsoid geometry promotes free rotation and helps maintain continuous agitation of solutions, suspensions and reaction mixtures in glassware used for synthesis, sample preparation and general laboratory work. These PTFE magnetic stirring bars from manufacturer Witeg are a standard consumable for magnetic stirrers and hotplate stirrers wherever an oval form factor is preferred for round-bottom flasks. Dimensions, material and pack configuration match the stated manufacturer data for routine laboratory stirring applications.

Questions about Magnetic stirring bar oval 15x30 mm
What is this article?
Magnetic stirring bar oval 15x30 mm is the article on this page. Luminix Health distributes Witeg 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.
