Description
Magnetic stirring bar, PTFE, 12 x 4,5 mm, cylindrical, small centre ring is a compact laboratory stirrer for controlled mixing of liquids and suspensions on magnetic stirrers. The bar measures 12 mm in length and 4,5 mm in diameter and features a cylindrical profile with a small centre ring that promotes centred rotation. It is manufactured from polytetrafluoroethylene (PTFE), providing an inert surface suitable for contact with a broad range of aqueous and organic media used in chemical and life-science work. The PTFE encapsulation fully encloses the internal magnet, protecting both the core and the sample. This size is well suited to small vessels, tubes and flasks where gentle yet effective agitation is required. Supplied in packs of 10 pieces from manufacturer Brand, the stirring bars support routine sample preparation, dissolution and reaction monitoring tasks. The round-bar geometry ensures consistent magnetic coupling with standard stirrer drives while the centre ring helps reduce friction against vessel bases during prolonged operation.

Questions about Magnetic stirring bar PTFE, 12 x 4,5 mm, cyl., small pivot ring
What is this article?
Magnetic stirring bar PTFE, 12 x 4,5 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.
