Description
Magnetic stirring bars with PTFE coating, flat profile, L 50 x d 8 mm, are laboratory stir bars designed for everyday mixing tasks on magnetic stirrers. Their flat geometry supports general-purpose stirring in a similar way to cylindrical bars, while generating less turbulence at low rotational speeds, which helps maintain calmer liquid surfaces and more controlled mixing in beakers, flasks and other vessels. The inert PTFE coating protects the magnetic core and offers broad chemical resistance for routine aqueous and organic work. Supplied as a practical pack of 5 pieces from manufacturer Labbox, these bars suit teaching labs, quality-control benches and research workflows where reliable, low-turbulence stirring is preferred. Net weight of the pack is 0,050 kg. Dimensions of 50 mm length and 8 mm diameter make them a versatile size for medium vessels. Use them wherever smooth, reproducible agitation is required without aggressive vortex formation at modest speeds.

Questions about Magnetic stirring bar, plain, l 50 x diam. 8 mm, 5 pcs
What is this article?
Magnetic stirring bar, plain, l 50 x diam. 8 mm, 5 pcs is the article on this page. Luminix Health distributes Labbox 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.
