Description
Magnetic stirring bar 35x6 mm is a cylindrical laboratory stir bar with a magnetic core coated in polytetrafluoroethylene (PTFE). It measures 35 mm in length and 6 mm in diameter, has smooth surfaces and is supplied without a centre ring in a clean round-rod form. The PTFE enclosure provides the chemical inertness typical of this material for contact with many aqueous and organic laboratory media during magnetic stirring. Packaged in sets of 10 pieces from manufacturer Marienfeld, the bars are intended for routine mixing in beakers, flasks and similar vessels on standard magnetic stirrers. Cylindrical geometry supports stable rotation and efficient liquid movement, while the smooth finish helps limit residue adhesion and simplifies cleaning between runs. The 35 mm length suits medium to larger laboratory vessels where controlled homogenisation is required. Absence of a centre ring leaves an uninterrupted cylindrical profile preferred in many everyday setups. Each pack delivers ten identical PTFE-coated units ready for general laboratory stirring work.

Questions about Magnetic stirring bars 35x6 mm,
What is this article?
Magnetic stirring bars 35x6 mm, is the article on this page. Luminix Health distributes Marienfeld 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.
