Description
Rotilabo® tablet-form style stirring magnets are PTFE-coated laboratory stir bars designed for reliable magnetic mixing in beakers, flasks, and other vessels. This model measures 40 mm in diameter and 14 mm in height, giving a compact tablet geometry that sits stably on the vessel base while providing effective coupling to standard magnetic stirrers and hotplate stirrers. The continuous PTFE coating protects the magnetic core from chemical attack and supports use across a wide range of aqueous and organic media common in routine laboratory work. Supplied as a single piece, the accessory is suitable for general chemistry, biochemistry, and sample-preparation benches where consistent stirring performance is required. The Rotilabo® tablet-form stir magnet from manufacturer ROTH SELECTION complements magnetic stirrer setups used in teaching labs, quality-control environments, and research facilities. Dimensions of Ø 40 mm and H 14 mm help match the bar to medium-volume vessels, balancing mixing efficiency with ease of retrieval after use. PTFE encapsulation also simplifies cleaning between experiments and reduces cross-contamination risk when protocols demand careful vessel hygiene.

Questions about Rotilabo®-tablet form style stir. magnet, PTFE-coated Ø 40 mm, H 14 mm
What is this article?
Rotilabo®-tablet form style stir. magnet, PTFE-coated Ø 40 mm, H 14 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.
