Description
Magnetic stirring bars with PTFE coating, octahedral form, L 75 x d 13 mm, are laboratory stir elements supplied in a pack of 30 pieces. Each bar combines octahedral geometry with a PTFE surface finish for everyday use on magnetic stirrers. The octahedral profile is specified for containers with a slightly curved or irregular bottom, aiding contact and rotation when the vessel base is not flat. Measuring 75 mm in length and 13 mm in diameter, the bars suit larger beakers, flasks and comparable vessels in chemical, biological and analytical laboratories. These magnetic stirring bars from manufacturer Labbox form part of the LBX INSTRUMENTS line and are packed in quantity for regular bench consumption. Net weight of the pack is 1,071 kg. Commonly called stir bars or stirring fleas, they allow shaft-free agitation of liquids and support sample preparation, dissolution and general mixing workflows in research, teaching and quality-control settings that depend on magnetic stirring equipment.

Questions about Magnetic stirring bar, octahedral, l 75 x diam. 13 mm, 30 pcs
What is this article?
Magnetic stirring bar, octahedral, l 75 x diam. 13 mm, 30 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.
