Description
Micro magnetic stirring bars with PTFE coating, L 5 x d 2 mm, are compact laboratory tools designed for magnetic agitation in very small containers. These miniature stir bars feature a protective PTFE coating surrounding the magnetic core, providing chemical resistance and a smooth outer surface for contact with common laboratory media. Offered in a pack of 10 pieces, they support convenient stocking for parallel experiments or routine sample preparation. Dimensions of 5 mm length and 2 mm diameter make them suitable for microcentrifuge tubes, small vials and other restricted geometries where larger bars cannot operate. From manufacturer Labbox, these bars belong to the LBX INSTRUMENTS range for everyday laboratory use. Their net weight of 0,003 kg reflects the micro-scale construction while still coupling reliably to standard magnetic stirrers. The PTFE surface reduces residue adhesion and aids clean handling between steps. In analytical chemistry, biochemistry and microscale work, controlled mixing of limited volumes is essential; these micro magnetic stirring bars meet that need without occupying excess space inside the vessel, helping laboratories maintain sample integrity when working in very small containers.

Questions about Magnetic stirring bar, micro, l 5 x diam. 2 mm, 10 pcs
What is this article?
Magnetic stirring bar, micro, l 5 x diam. 2 mm, 10 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.
