Description
Magnetic stirring bar, PTFE, 20 x 6 mm, cylindrical, small centre ring provides robust mixing capability for laboratory vessels on magnetic stirrers. With dimensions of 20 mm length and 6 mm diameter, the cylindrical design includes a small centre ring that supports centred rotation and reduces contact friction. The bar is made from polytetrafluoroethylene (PTFE), delivering an inert surface suitable for use with diverse aqueous and organic media in chemical, pharmaceutical and biological applications. Full PTFE encapsulation protects the internal magnet and maintains sample integrity. This size is appropriate for medium-volume beakers, flasks and reaction vessels requiring thorough yet controlled agitation. Supplied as a pack of 10 pieces from manufacturer Brand, the stirring bars are convenient for routine laboratory operations such as sample preparation, dissolution and continuous mixing. The round-bar geometry promotes strong magnetic coupling with standard drive units and consistent spinning performance throughout extended stirring cycles.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about Magnetic stirring bar PTFE, 20 x 6 mm, cyl., small pivot ring
What is this article?
Magnetic stirring bar PTFE, 20 x 6 mm, cyl., small pivot ring is the article on this page. Luminix Health distributes Brand 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.
