Description
Rotilabo® magnetic stirring rod, cylindrical, is a PTFE-coated stir bar for magnetic stirrers used throughout laboratory sample preparation and synthesis support. This cylindrical variant measures 12 mm in diameter and 55 mm in length, offering a larger contact profile for efficient mixing in medium-sized vessels. The PTFE coating shields the internal magnet and contributes chemical resistance when stirring aqueous solutions and many common laboratory solvents. Intended as an accessory for magnetic stirrers, it enables sealed, shaft-free agitation in beakers, flasks and bottles. Supplied as one piece from manufacturer ROTH SELECTION in the Rotilabo® range, the rod fits standard labware and laboratory-appliance setups. The 12 mm × 55 mm cylindrical geometry is suited to applications that benefit from stronger torque transfer and stable rotation compared with smaller bars. Unit quantity is one piece, with an approximate weight of 0,027 kg. Laboratories standardising magnetic stirring accessories can select this PTFE-coated cylindrical rod when a 12 mm diameter and 55 mm length specification is needed for reliable day-to-day mixing.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about Rotilabo®-magn.stirring rod, cylindrical, PTFE-coated, Ø 12 mm, length 55 mm
What is this article?
Rotilabo®-magn.stirring rod, cylindrical, PTFE-coated, Ø 12 mm, length 55 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.
