Description
Oval magnetic stirring bar, PTFE-coated, 30 x 11 mm is a laboratory stirring element intended for effective mixing in round-bottom flasks and comparable vessels. Inside, an ALNICO magnet—an alloy of aluminium, nickel, iron and cobalt—is fully encapsulated in a PTFE coating that isolates the magnet from the working medium. The elliptical form provides strong mixing performance, particularly in flasks with curved bases, while polished surfaces aid stable centring and smooth, continuous rotation. Close contact with the vessel floor helps limit the chance of the bar jumping during stirring. Supplied as a single piece from manufacturer ISOLAB Laborgeräte, this oval stirring bar suits a wide range of routine laboratory agitation needs. The PTFE shell offers chemical resistance and low-friction running, supporting reliable use in sample preparation, dissolution and general magnetic-stirrer applications.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about magnetic stirring bar - oval - 30x11 mm
What is this article?
magnetic stirring bar - oval - 30x11 mm is the article on this page. Luminix Health distributes ISOLAB 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.
