Description
Magnetic stirring bars with PTFE coating in oval form, length 40 mm and diameter 20 mm, are designed for magnetic stirring applications in the laboratory. Supplied in packs of 5 pieces, they offer a convenient quantity for routine workstations. The PTFE coating supplies a chemically resistant envelope for the magnetic core, limiting contact between the bar and process liquids. Their oval profile makes them particularly suitable for round-bottom flasks, where the geometry aids smooth motion and efficient mixing. Available from manufacturer Labbox in the LBX INSTRUMENTS series, these stirrers address standard agitation, dissolution and homogenisation needs in chemistry, life-science and analytical environments. Pack net weight is 0,050 kg. At 40 mm by 20 mm they are sized for somewhat larger medium-volume vessels while still coupling reliably to the magnetic drive. These oval PTFE-coated stirring bars provide a clear, practical option whenever consistent liquid mixing in round-bottom glassware is required as part of daily laboratory practice.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about Magnetic stirring bar, oval, l 40 x diam. 20 mm, 5 pcs
What is this article?
Magnetic stirring bar, oval, l 40 x diam. 20 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.
