Description
Oval magnetic stirring bar, PTFE-coated, 35 x 12 mm is a laboratory stirring element built for efficient mixing in round-bottom flasks and similar glassware. An ALNICO magnet—an alloy of aluminium, nickel, iron and cobalt—forms the core and is completely encapsulated in a PTFE coating that protects it from the process liquid. Elliptical geometry yields very good mixing action, especially in vessels with rounded bottoms, and the polished surface supports consistent centring with smooth, uninterrupted stirring. Firm contact with the flask base reduces the risk of the bar jumping or losing drive during operation. This oval stirring bar from manufacturer ISOLAB Laborgeräte is supplied as one piece and is suited to everyday laboratory mixing tasks. PTFE encapsulation combines chemical resistance with low friction, making the bar a practical option for sample preparation, dissolution and reaction work on magnetic stirrers.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about magnetic stirring bar - oval - 35x12 mm
What is this article?
magnetic stirring bar - oval - 35x12 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.
