Description
Magnetic stirring bar, PTFE, 38 x 8 mm, octagonal, with centre ring is engineered for effective mixing of larger liquid volumes on laboratory magnetic stirrers. The bar measures 38 mm in length and 8 mm in diameter and features an octagonal cross-section together with a centre ring that stabilises rotation and improves contact with the vessel floor. Made from polytetrafluoroethylene (PTFE), it exhibits high chemical resistance, allowing safe use with many aqueous and organic reagents without degradation of the coating. The longer 38 mm profile combined with the centre-ring design delivers strong torque transmission and helps prevent the bar from wandering or stalling during prolonged stirring. Packaged in units of 10 pieces from manufacturer Brand, these stirring bars serve chemistry, life-science and industrial laboratories that require reliable homogenisation, dissolution or suspension of samples. The inert PTFE surface protects the internal magnet while remaining easy to clean between runs. The 38 mm × 8 mm dimensions suit a variety of flasks and beakers, providing consistent mixing performance for routine and preparative work where stable, centred agitation is essential.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about Magnetic stirring bar PTFE, 38 x 8 mm, octagonal, pivot ring
What is this article?
Magnetic stirring bar PTFE, 38 x 8 mm, octagonal, 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.
