Description
Magnetic stirring bar, PTFE, cylindrical, L x Ø 50 x 7 mm is a versatile laboratory stirrer designed for reliable mixing in a wide range of vessels and media. The cylindrical rod form features a smooth surface that supports consistent rotation and easy cleaning between runs. Manufactured from opaque PTFE, the bar combines chemical resistance with a maximum operating temperature of +270 °C, making it suitable for many routine and elevated-temperature stirring tasks. Strong permanent-magnet performance and a durable construction support long service life under continuous laboratory use. Dimensions are 50 mm in length and 7 mm in diameter, with a net weight of 0,007 kg. Supplied as 1 pc, this stirring bar from manufacturer Bürkle fits standard magnetic stirrers and is well suited to general chemistry, sample preparation, and process work where a classic cylindrical PTFE profile is preferred. Its smooth finish and robust magnet core help maintain stable coupling and efficient mixing across typical bench-scale applications.

Questions about Magnetic stirring bar, PTFE, cylindr., LxØ 50x7 mm
What is this article?
Magnetic stirring bar, PTFE, cylindr., LxØ 50x7 mm is the article on this page. Luminix Health distributes Bürkle 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.
