Description
Magnetic stirring bar in cylindrical form measures 7 mm in length by 2 mm in diameter and is manufactured from chemically inert polytetrafluoroethylene (PTFE). The smooth PTFE coating protects the embedded magnet while providing broad chemical resistance for everyday laboratory mixing tasks in small vessels, vials and micro-reactors. Its compact cylindrical geometry ensures stable rotation and efficient mixing even in limited liquid volumes. Supplied in practical packs of 10 pieces, these miniature stirring bars from manufacturer Brand are suitable for a wide range of aqueous and organic media under standard magnetic stirrer conditions. The robust PTFE surface resists adhesion and is easy to clean, supporting repeated use in research, quality-control and educational laboratories. Precise dimensions guarantee reliable performance across common hotplate and overhead magnetic drive systems without introducing metallic contamination into sensitive samples.

Questions about Magnetic stirring bar PTFE, 7 x 2 mm, cylindrical
What is this article?
Magnetic stirring bar PTFE, 7 x 2 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.
