Description
Magnetic stirring bar, PTFE, 70 x 8,5 mm, cylindrical, small centre ring is a laboratory stir bar intended for magnetic mixing applications. It measures 70 mm in length and 8,5 mm in diameter, with a cylindrical round-bar form and a small centre ring. The bar is made from polytetrafluoroethylene (PTFE). These dimensions and the centre-ring design support stable rotation when used with magnetic stirrers in beakers, flasks and similar vessels. Offered in a pack of 10 pieces from manufacturer Brand, the stirring bar suits routine mixing tasks in chemical, analytical and life-science laboratories. The PTFE construction provides a chemically resistant outer surface for contact with a variety of laboratory media, while the cylindrical profile with small centre ring helps maintain centred spinning. This 70 x 8,5 mm size is appropriate for medium-volume containers requiring consistent agitation without mechanical shafts. The product belongs to the standard range of PTFE magnetic stirring bars used for sample preparation, dissolution and reaction mixing workflows.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about Magnetic stirring bar PTFE, 70 x 8,5 mm, cyl., small pivot ring
What is this article?
Magnetic stirring bar PTFE, 70 x 8,5 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.
