Description
Cylindrical magnetic stirring bar 3 x 6 mm is a compact laboratory stir bar for controlled mixing in small vessels, vials and narrow-neck flasks. It features an outer diameter of 3 mm and a length of 6 mm in a round-rod cylindrical form, giving stable magnetic coupling on standard magnetic stirrers while occupying minimal working volume. The bar is fully encapsulated in polytetrafluoroethylene (PTFE), providing an inert contact surface with broad chemical resistance toward many acids, bases and organic solvents used in analytical and synthetic work. Pack size is 10 pc(s), suited to routine laboratory replenishment. These stirring bars from manufacturer Witeg support reproducible agitation in research, quality-control and teaching environments where low-mass, chemically resistant stir elements are required. The smooth cylindrical profile helps reduce wall friction and promotes steady rotation at typical laboratory speeds. Approximate net weight is 0,001 kg per piece. The PTFE encapsulation protects the magnetic core and simplifies cleaning between experiments, making the bar a practical choice for aqueous and non-aqueous media that demand inert wetted surfaces and reliable day-to-day performance in micro-scale and small-volume setups.

Questions about Magnetic stirring bar cylindrical 3x6mm
What is this article?
Magnetic stirring bar cylindrical 3x6mm 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.
