Description
Magnetic stirring bars with PTFE coating, cylindrical form, length 40 mm and diameter 8 mm, are designed for reliable magnetic mixing across routine laboratory workflows. PTFE encapsulation isolates the magnetic core from the process medium and provides chemical resistance toward many aqueous reagents and organic solvents used in daily bench chemistry. A pack of 30 pieces supplies multi-station stirring setups, teaching laboratories, and central stockrooms that benefit from uniform bar geometry for comparable mixing behaviour. The cylindrical profile is appropriate for flat-bottom beakers and similar vessels, encouraging stable spin when dimensions and stirrer speed are correctly matched to the vessel. These bars from manufacturer Labbox are specified for general laboratory use, combining a magnetic core with a smooth PTFE surface that is easy to rinse and reuse under standard cleaning procedures. Net pack weight is 0,204 kg, reflecting a practical bulk quantity for shared instrument areas. Well suited to chemistry, biology, and quality-control environments needing durable cylindrical stir bars with defined length and diameter for everyday sample agitation.

Questions about Magnetic stirring bar, cylindrical, l 40 x diam. 8 mm, 30 pcs
What is this article?
Magnetic stirring bar, cylindrical, l 40 x diam. 8 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.
