Description
Magnetic stirring bar with ring 5 x 15 mm is a PTFE-coated cylindrical stir bar intended for reliable magnetic mixing in laboratory glassware and plastic vessels. It has a diameter of 5 mm and a length of 15 mm, giving a slightly elongated profile that supports effective vortex formation while remaining suitable for moderate vessel volumes. The integrated centre ring assists stable rotation on the stirrer drive and helps reduce abrasion at the contact point with the vessel base. Encapsulation in polytetrafluoroethylene (PTFE) provides chemical inertness and resistance across a wide range of aqueous and organic media used in synthesis, sample preparation, and quality control. Round rod form ensures consistent coupling with conventional magnetic stirrers and hotplate stirrers. Offered in packs of 10 pc(s) from manufacturer Witeg, these stirring bars are practical consumables for chemistry and life-science laboratories. Net weight is 0,004 kg. The 5 × 15 mm ringed design combines compact dimensions with dependable mixing performance for day-to-day laboratory applications.

Questions about Magnetic stirring bars with ring 5 x 15 mm
What is this article?
Magnetic stirring bars with ring 5 x 15 mm 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.
