Description
Magnetic stirring bars with PTFE coating in an oval form, 20 x 10 mm, deliver practical mixing performance for magnetic stirrer applications. The oval shape is particularly suitable for round-bottom flasks, allowing the bar to follow the curved base and promote consistent agitation of liquids. PTFE encapsulation shields the magnetic core and provides a chemically resistant contact surface for everyday laboratory media. This pack supplies 30 pc(s) with a net weight of 0,114 kg, which is convenient for multi-user laboratories, teaching suites, and facilities that keep spare bars at several benches. The set comes from manufacturer Labbox as part of the LBX INSTRUMENTS range and fits routine stirring tasks in chemistry, biology, and analytical sample work. Dimensions of 20 mm by 10 mm match small to medium vessels used with standard magnetic hotplate stirrers. The smooth PTFE exterior supports simple cleaning between experiments and helps maintain bar integrity during repeated use. Larger pack quantity reduces reorder frequency while keeping oval PTFE stir bars ready for continuous laboratory operations that depend on stable magnetic mixing.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about Magnetic stirring bar, oval, l 20 x diam. 10 mm, 30 pcs
What is this article?
Magnetic stirring bar, oval, l 20 x diam. 10 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.
