Description
Magnetic stirring bars with PTFE coating in a flat profile, length 40 mm and diameter 8 mm, are designed for controlled agitation in laboratory glassware and process vessels. Provided as a multipack of 30 pieces, these flat bars serve general mixing duties similar to cylindrical magnetic stirring bars, yet they create less turbulence at low rotational speeds. An inert PTFE coating encloses the magnetic core, offering chemical resistance toward aqueous media and many organic solvents typical of research, QC and educational laboratories. The flat geometry encourages stable rotation on the stirrer drive, supports uniform mixing and helps minimise strong vortex formation during gentle agitation. They fit standard beakers, Erlenmeyer flasks and comparable containers used with magnetic stirrers or hotplate stirrers for dissolution, homogenisation and sample preparation. These stirring bars from manufacturer Labbox combine a robust PTFE finish with a high piece count suited to busy benches. Net weight of the pack is 0,195 kg. The bars are easy to clean and reuse under ordinary laboratory conditions without special accessories.

Questions about Magnetic stirring bar, plain, l 40 x diam. 8 mm, 30 pcs
What is this article?
Magnetic stirring bar, plain, l 40 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.
