Description
Magnetic stirring bar, cylindrical, PTFE coated, approx. 70 x 10 mm is designed for dependable agitation on laboratory magnetic stirrers. The elongated cylindrical profile generates a stable vortex and thorough mixing within larger beakers, flasks and reaction vessels. Encased in a continuous PTFE layer, the magnetic core remains protected from chemical attack by solvents, reagents and aqueous buffers, while the outer surface stays low-friction and simple to clean. Approximate overall size of 70 mm length by 10 mm diameter suits medium- to larger-volume laboratory tasks. Delivered as a single unit from manufacturer Hecht, the bar fits seamlessly into daily chemical, analytical and preparative routines. Chemical inertness of the PTFE coating helps preserve sample integrity and reduces carry-over between successive uses. The symmetrical cylindrical shape encourages smooth, centred rotation at customary stirring speeds, supporting homogeneous suspensions and solutions. This PTFE-coated magnetic stirring bar supplies a robust, chemically resistant accessory for everyday laboratory mixing requirements.

Questions about Magnetic stirring bars, cylindrical, PTFE coated ca. 70 x 10 mm
What is this article?
Magnetic stirring bars, cylindrical, PTFE coated ca. 70 x 10 mm is the article on this page. Luminix Health distributes Hecht 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.
