Description
Magnetic stirring bars with PTFE coating, flat profile, L 25 x d 8 mm, are laboratory stirring elements for general use on magnetic stirrers. They serve the same broad purpose as cylindrical magnetic stirring bars, while the flat geometry is intended to produce less turbulence at low rotational speeds, aiding calmer mixing in sensitive or gently stirred preparations. A continuous PTFE coating shields the magnetic core and presents a chemically resistant surface for contact with typical laboratory solutions. With a length of 25 mm and a diameter of 8 mm, these bars suit medium-small vessels and standard bench-scale volumes where a slightly larger flat stirrer improves coupling and coverage. Supplied in a pack of 5 pieces from manufacturer Labbox as part of the LBX INSTRUMENTS range, the set has a net weight of 0,050 kg and is straightforward to store with other stirring accessories. Well suited to chemistry, biology, and analytical laboratories that require reliable flat PTFE stirring bars for everyday low-turbulence agitation.

Questions about Magnetic stirring bar, plain, l 25 x diam. 8 mm, 5 pcs
What is this article?
Magnetic stirring bar, plain, l 25 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.
