Description
Rotilabo® magnetic stirring rod, cylindrical, is a PTFE-coated laboratory stir bar for use with magnetic stirrers in routine mixing applications. The cylindrical geometry measures 8 mm in diameter and 20 mm in length, making it suitable for small vessels, vials and compact reaction setups where controlled agitation is required. The inert PTFE coating protects the magnetic core and provides broad chemical resistance during stirring of aqueous and many organic media at the bench. Supplied as a single piece, this accessory complements magnetic stirrer platforms used across chemistry, biochemistry and general laboratory workflows. From manufacturer ROTH SELECTION under the Rotilabo® line, the rod offers a standard cylindrical profile that couples reliably with common stirrer drive fields. Compact dimensions support efficient mixing in limited liquid volumes without excessive vortexing. With a unit weight of 0,006 kg and a pack size of one piece, the Rotilabo® cylindrical magnetic stirring rod is a practical consumable accessory for laboratories equipping or replenishing magnetic stirrer setups.

Questions about Rotilabo®-magn.stirring rod, cylindrical, PTFE-coated, Ø 8 mm, length 20 mm
What is this article?
Rotilabo®-magn.stirring rod, cylindrical, PTFE-coated, Ø 8 mm, length 20 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.
