Description
Magnetic stirring bars with PTFE coating, octahedral shape, length 25 mm and diameter 8 mm, are laboratory stir bars for everyday magnetic mixing. This pack contains 30 pieces and is intended for vessels with slightly curved or irregular bottoms, where the octahedral profile helps the bar stay centred and rotate smoothly. The PTFE coating shields the magnetic core and offers broad chemical resistance during routine stirring of aqueous and many organic media. With a pack net weight of 0,138 kg, the set is a practical stock item for chemistry, biology, pharmaceutical, and analytical laboratories that need consistent agitation for dissolution, sample preparation, and reaction work. These magnetic stirring bars from manufacturer Labbox belong to the LBX INSTRUMENTS line and suit hotplate stirrers and multipoint systems alike. Compact dimensions make them suitable for smaller flasks, beakers, and tubes while still delivering reliable magnetic coupling. Use them wherever durable, chemically inert stir bars in a defined octahedral geometry are required for reproducible laboratory workflows.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about Magnetic stirring bar, octahedral, l 25 x diam. 8 mm, 30 pcs
What is this article?
Magnetic stirring bar, octahedral, l 25 x diam. 8 mm, 30 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.
