Description
Magnetic stirring bars with PTFE coating, triangular profile, length 50 mm and diameter 12 mm, are compact laboratory stirrers intended for magnetic stirrers and stirring hotplates. The triangular geometry promotes vigorous bottom flow, making the bars especially suitable for dissolving solids and redispersing sediments in round-bottom flasks, beakers and reaction vessels. A continuous PTFE coating isolates the magnet core from aggressive chemicals, limits sample carry-over and supports clean handling between runs. Supplied in a pack of 5 pieces from manufacturer Labbox, the set is convenient for method development, small work groups or dedicated instrument stations. The 50 × 12 mm size offers stable magnetic coupling over typical laboratory speed ranges while remaining easy to retrieve with a stirring-bar retriever. Net weight of the pack is 0,050 kg. Belonging to the LBX INSTRUMENTS line, these triangular PTFE bars give a chemically resistant, ready-to-use solution for dissolution, homogenisation and sediment-mixing tasks in analytical, biotech and industrial laboratories.

Questions about Magnetic stirring bar, triangular, l 50 x diam. 12 mm, 5 pcs
What is this article?
Magnetic stirring bar, triangular, l 50 x diam. 12 mm, 5 pcs is the article on this page. Luminix Health distributes Labbox 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.
