Description
Magnetic stirring bar cylindrical 6 x 20 mm is a PTFE-encapsulated laboratory stir bar intended for efficient magnetic mixing in beakers, flasks and reaction vessels of moderate size. With an outer diameter of 6 mm and a length of 20 mm, the cylindrical round-rod profile delivers stable coupling to magnetic stirrers and promotes a uniform vortex during dissolution, titration and general sample preparation. Polytetrafluoroethylene (PTFE) encapsulation provides chemical resistance against a wide range of laboratory reagents, including many acids, bases and solvents, while the smooth outer surface aids cleaning and reduces carry-over between experiments. Supplied as a pack of 10 pieces from manufacturer Witeg, the bars are suitable for routine analytical work, synthetic chemistry steps and teaching laboratories that require durable, chemically inert stirring elements. Net weight is 0,004 kg. The 6 × 20 mm cylindrical geometry balances mixing performance with vessel compatibility, supporting consistent agitation in everyday research, quality-control and educational applications where reliable magnetic stirring is essential.

Questions about Magnetic stirring bar cylindrical 6x20mm
What is this article?
Magnetic stirring bar cylindrical 6x20mm is the article on this page. Luminix Health distributes Witeg 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.
