Description
Magnetic stirring bar, PTFE, 159 x 27 mm, cylindrical is a robust laboratory stirring element designed for reliable mixing in a wide range of vessels and media. Manufactured from chemically inert polytetrafluoroethylene (PTFE), the bar resists aggressive solvents, acids and bases while providing a smooth, non-stick surface that minimises sample adhesion and simplifies cleaning. Its cylindrical profile (Stabform rund) with a length of 159 mm and a diameter of 27 mm delivers stable rotation and efficient vortex formation on standard magnetic stirrers. The generous dimensions make it particularly suitable for larger flasks, beakers and reaction vessels where thorough homogenisation is required. Supplied as a single piece from manufacturer Brand, this stirring bar supports everyday laboratory workflows in chemistry, biochemistry and quality-control environments. The PTFE encapsulation protects the internal magnet from corrosion and ensures long service life under continuous use. Ideal for aqueous and organic systems alike, it maintains consistent performance without introducing metallic contamination.

Questions about Magnetic stirring bar PTFE, 159 x 27 mm, cylindrical
What is this article?
Magnetic stirring bar PTFE, 159 x 27 mm, cylindrical 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.
