Description
Rotilabo® ellipsoidal magnetic stirring rods are PTFE-coated laboratory stirrer bars intended for use with magnetic stirrers. Each rod has a diameter of 20 mm and a length of 64 mm, giving an elongated ellipsoidal profile that promotes smooth mixing in flasks, beakers and reaction vessels. The inert PTFE coating protects the magnetic core and limits interaction with common laboratory solvents and reagents. These Rotilabo® rods from manufacturer ROTH SELECTION support everyday stirring tasks in synthesis, sample preparation and dissolution work. The ellipsoidal geometry helps maintain stable rotation and efficient mass transfer across a range of vessel sizes typically found on the laboratory bench. Choose this format when a durable, chemically resistant magnetic stirring element of defined dimensions is required for routine mixing applications.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about Rotilabo®-ellipsoidal magn. stirr. rods, PTFE-coated, Ø 20 mm, length 64 mm
What is this article?
Rotilabo®-ellipsoidal magn. stirr. rods, PTFE-coated, Ø 20 mm, length 64 mm is the article on this page. Luminix Health distributes Carl Roth 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.
