Description
Rotilabo® magnetic bar with centre ring is a cylindric stir bar accessory for magnetic stirring in the laboratory. The bar has a diameter of 8 mm and a length of 40 mm, giving a compact profile suitable for smaller vessels and controlled mixing volumes. The centre-ring design helps the bar track smoothly on the magnetic drive and supports stable rotation during routine stirring. This format is a standard accessory for magnetic stirrers used in chemistry, biology, and general laboratory preparation work. Stated weight is 0,010 kg. With clearly defined cylindric geometry—Ø 8 mm and 40 mm length—the Rotilabo® magnetic bar with centre ring integrates cleanly into everyday liquid-handling and stirring setups where reliable magnetic coupling and a centred ring profile are required for consistent agitation of solutions and suspensions.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about Rotilabo® magnetic bar with centre ring, cylindric, Ø 8 mm, length 40 mm
What is this article?
Rotilabo® magnetic bar with centre ring, cylindric, Ø 8 mm, length 40 mm is the article on this page. Luminix Health distributes Carl Roth 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.
