Description
Magnetic stirring bars with PTFE coating, cylindrical form, length 40 mm and diameter 8 mm, deliver dependable mixing for general laboratory applications. The inert PTFE jacket protects the internal magnet and withstands contact with many aqueous solutions and common organic solvents encountered in routine sample preparation. Supplied in a convenient pack of 5 pieces, this format suits individual workstations, method development, or smaller laboratories that prefer modest stock levels without bulk packaging. The cylindrical geometry works well in flat-bottom vessels and standard beakers, supporting steady rotation when bar size is chosen to match vessel diameter and magnetic stirrer settings. Offered by manufacturer Labbox for general use, the bars combine a magnetic core with continuous PTFE encapsulation for chemical resistance and straightforward cleaning between experiments. Net weight of the pack is 0,035 kg, making the set easy to store beside hotplate stirrers. Suitable for chemistry, life-science, and analytical benches that require consistent cylindrical stir bars with defined length and diameter for everyday mixing tasks.

Questions about Magnetic stirring bar, cylindrical, l 40 x diam. 8 mm, 5 pcs
What is this article?
Magnetic stirring bar, cylindrical, l 40 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.
