Description
Magnetic stirring bar, PTFE, 15 x 4,5 mm, cylindrical is a cylindrical laboratory stir bar measuring 15 mm in length and 4,5 mm in diameter. Manufactured from polytetrafluoroethylene (PTFE), this round-rod form stirring bar is intended for use with magnetic stirrers to agitate liquids in beakers, flasks, vials and similar vessels. The PTFE material provides a chemically inert outer surface around the internal magnet, making the bar suitable for a broad range of aqueous and organic media commonly encountered in research and analytical work. Offered in a convenient pack of 10 pieces from manufacturer Brand, the bars support routine mixing, dissolution and homogenisation tasks in chemistry, life-science and quality-control laboratories. Their compact cylindrical geometry promotes stable rotation and efficient mass transfer even in small-volume containers. Net weight is 0,007 kg. These stirring bars form part of standard laboratory consumables for reproducible sample preparation and process control where gentle yet thorough agitation is required.

Questions about Magnetic stirring bar PTFE, 15 x 4,5 mm, cylindrical
What is this article?
Magnetic stirring bar PTFE, 15 x 4,5 mm, cylindrical 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.
