Description
Magnetic stirring bar, PTFE, 70 x 20 mm, elliptical is a robust laboratory mixing tool designed for effective agitation of solutions in a variety of glassware. With a length of 70 mm and a diameter of 20 mm, this ellipsoid PTFE stir bar generates a strong, stable vortex on magnetic stirrers while reducing the risk of decoupling at higher speeds. The continuous polytetrafluoroethylene coating confers exceptional resistance to corrosive chemicals, organic solvents and elevated temperatures, protecting the embedded magnet and preventing sample contamination. Its elliptical profile ensures smooth spinning and thorough blending of both low- and high-viscosity media. Supplied in convenient packs of 10 pc(s), the bars are ideal for routine sample preparation, synthesis and analytical procedures in chemistry, life-science and industrial laboratories. Produced by Brand, each stirring bar combines durable construction with reliable magnetic coupling for consistent day-to-day performance. The 70 mm × 20 mm size accommodates medium to larger vessels, making it a versatile choice across multiple experimental scales. These PTFE elliptical magnetic stirring bars deliver dependable, chemically inert mixing essential for accurate and reproducible results.

Questions about Magnetic stirring bar PTFE, 70 x 20 mm, oval
What is this article?
Magnetic stirring bar PTFE, 70 x 20 mm, oval is the article on this page. Luminix Health distributes Brand 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.
