Description
Magnetic stirring bar with ring 6 x 30 mm is a cylindrical laboratory stir bar with centre ring for consistent performance on magnetic stirrers. It has a diameter of 6 mm and a length of 30 mm in a round rod form that works well in flasks, beakers and similar vessels. Encapsulated in polytetrafluoroethylene (PTFE), the bar provides chemical resistance appropriate for aqueous media and many organic solvents used in analytical chemistry, synthesis and quality-control laboratories. The centre ring assists stable, centred rotation and reduces wear against the vessel base during continuous mixing. Available in packs of 10 pc(s) from manufacturer Witeg, these bars are suited to routine stirring of small to medium sample volumes on the bench. The smooth PTFE exterior is straightforward to clean and helps limit residue transfer between experiments. At a net weight of 0,004 kg, each unit stays light yet magnetically effective for everyday laboratory agitation tasks.

Questions about Magnetic stirring bar with ring 6x30mm
What is this article?
Magnetic stirring bar with ring 6x30mm 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.
