Description
Magnetic stirring bars with PTFE coating, octahedral profile, L 22 x d 8 mm, are compact laboratory stirrers for everyday magnetic mixing. The octahedral geometry supports stable rotation and efficient turbulence, and is intended for vessels with a slightly curved or irregular bottom where cylindrical bars may skate or stall. A continuous PTFE coating shields the magnetic core and offers broad chemical resistance during routine stirring of aqueous solutions and many common laboratory media. This pack contains 5 pieces, suited to multi-position stirrers, shared benches, or stock replenishment in research, QC, and teaching labs. The L 22 x d 8 mm format couples well with standard drive magnets in beakers, flasks, and bottles of moderate volume. These bars from manufacturer Labbox form part of the LBX INSTRUMENTS range and are selected when dependable mixing in non-flat vessels is required. Net weight of the pack is 0,050 kg. Use them for dissolution, suspension, buffer preparation, and general sample homogenisation on magnetic stirrers.

Questions about Magnetic stirring bar, octahedral, l 22 x diam. 8 mm, 5 pcs
What is this article?
Magnetic stirring bar, octahedral, l 22 x diam. 8 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.
