Description
Cylindrical magnetic stirring bars with PTFE coating, length 20 mm and diameter 7 mm, enable reliable mixing on standard laboratory magnetic stirrers. Every bar encloses a magnetic core in PTFE, delivering chemical resistance and low adhesion for general laboratory applications. The pack of 30 pieces is well suited to busy analytical, research and teaching environments that need multiple stirrers available at once. The cylindrical geometry encourages stable spinning in beakers, flasks and other common vessels. PTFE coating keeps the contact surface inert toward aqueous media and many routine solvents. These stirring bars from manufacturer Labbox are part of the LBX Instruments range and intended for everyday bench use. Net pack weight is 0,010 kg, so the set remains easy to handle and store. Uniform dimensions support consistent mixing behaviour from run to run. Laboratories rely on PTFE-coated cylindrical magnetic stirring bars for homogenisation, dissolution and sample preparation where chemical compatibility and smooth rotation are fundamental requirements.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about Magnetic stirring bar, cylindrical, l 20 x diam. 7 mm, 30 pcs
What is this article?
Magnetic stirring bar, cylindrical, l 20 x diam. 7 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.
