Description
Magnetic stirring bars with PTFE coating, oval, L 30 x d 16 mm are laboratory stir bars for controlled mixing on magnetic stirrers. The PTFE coating offers chemical resistance while the oval shape aids stable rotation in curved vessels. Measuring 30 mm in length and 16 mm in diameter, these bars are particularly suitable for round-bottom flasks, where the profile helps keep the bar centred and improves agitation efficiency. Supplied as a pack of 5 pieces from manufacturer Labbox, they suit smaller workflows, method development or dedicated instrument setups. PTFE-coated oval stir bars are commonly applied when dissolving reagents, blending solvents or maintaining homogeneous suspensions without metal contact with the sample. Compared with cylindrical designs, the oval geometry is better matched to flask bottoms and similar curved containers. Net pack weight is 0,050 kg. Use them on standard magnetic hotplate stirrers for synthesis support, sample preparation and general laboratory stirring where inert surfaces and dependable mixing behaviour are needed.

Questions about Magnetic stirring bar, oval, l 30 x diam. 16 mm, 5 pcs
What is this article?
Magnetic stirring bar, oval, l 30 x diam. 16 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.
