Description
Magnetic stirring bar with ring 6 x 35 mm is a cylindrical laboratory stir bar for controlled mixing on magnetic stirrers and hotplate stirrers. With an outer diameter of 6 mm and a length of 35 mm, the round-rod geometry includes a centre ring that supports stable spinning and helps limit contact with vessel bases during continuous operation. The bar is encapsulated in polytetrafluoroethylene (PTFE), giving broad chemical resistance for aqueous buffers, solvents, and routine process media used in research, analytical, and quality-control laboratories. Packaged as 10 pc(s), the format suits multi-station benches and shared preparation areas where several vessels run in parallel. Each piece has a net weight of 0,006 kg, so handling and inventory checks remain straightforward. This magnetic stirring bar with ring from manufacturer Witeg is intended for dissolution, homogenisation, and sample conditioning in beakers, flasks, and similar open vessels. The PTFE surface cleans readily between media changes and supports hygienic workflow practices. Laboratories that need a compact 6 x 35 mm stir bar with defined dimensions and a centre ring will find this model a practical everyday consumable for life-science, pharmaceutical, and industrial chemistry applications.

Questions about Magnetic stirring bar with ring 6x35mm
What is this article?
Magnetic stirring bar with ring 6x35mm 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.
