Description
Magnetic stirring bar, PTFE, 40 x 20 mm, elliptical is a robust laboratory accessory engineered for efficient mixing in a variety of glass and plastic vessels. With a length of 40 mm and a diameter of 20 mm, the ellipsoid form delivers stable spinning action and thorough liquid circulation, even in round-bottom flasks. The bar is made entirely of polytetrafluoroethylene (PTFE), providing excellent resistance to corrosive chemicals, strong acids and organic media encountered in research and quality-control settings. This chemical inertness helps maintain sample integrity during prolonged stirring. The smooth PTFE exterior further aids cleaning and reduces carry-over between runs. Offered in packs of 10 pieces from manufacturer Brand, these elliptical magnetic stirring bars integrate readily with conventional magnetic stirrers and combination hotplate units. Their intermediate dimensions make them versatile for medium-scale preparations, dissolution studies and general laboratory workflows that demand dependable, non-contaminating agitation.

Questions about Magnetic stirring bar PTFE, 40 x 20 mm, oval
What is this article?
Magnetic stirring bar PTFE, 40 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.
