Description
Magnetic stirring bar, cylindrical, PTFE coated, approx. 40 x 8 mm is designed for effective mixing of larger liquid volumes on laboratory magnetic stirrers. The robust cylindrical shape and complete PTFE encapsulation provide chemical resistance together with low-friction, stable rotation inside beakers, flasks and reaction vessels. Approximate dimensions of 40 x 8 mm make the bar appropriate for medium- to larger-scale stirring tasks encountered in synthesis, dissolution and sample homogenisation. Supplied as 1 pc, it constitutes a ready-to-deploy accessory for hotplate stirrers and multi-position drive systems. The inert PTFE surface protects the internal magnet, reduces residue build-up and facilitates thorough rinsing between experiments, thereby limiting cross-contamination. Available from manufacturer Hecht, this stirring bar delivers consistent magnetic coupling and efficient energy transfer for homogeneous blending. Its larger cylindrical profile promotes strong vortex formation while remaining compatible with aqueous solutions and a broad range of organic media. Ideal for research, process-development and quality-control laboratories that require durable, chemically inert stirring elements of defined size.

Questions about Magnetic stirring bars, cylindrical, PTFE coated ca. 40 x 8 mm
What is this article?
Magnetic stirring bars, cylindrical, PTFE coated ca. 40 x 8 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.
