Description
Rotilabo® magnetic bar with centre ring is a cylindrical stir bar for magnetic stirrers used in laboratory mixing. Diameter is 8 mm and length is 45 mm, with a centre ring that helps keep the bar centred and reduces wall contact while spinning. The centre-ring geometry supports steady rotation under a magnetic drive and is a common choice when selecting stir bars for small to medium vessels. From manufacturer ROTH SELECTION, this Rotilabo® bar belongs to the accessories range for magnetic stirrers in chemistry, biology, and analytical laboratories. Cylindrical form together with the stated Ø 8 mm and 45 mm length allows matching to vessel size and liquid volume. Laboratories can keep the single-piece unit as a replacement or as part of a mixed stir-bar set. Low mass of 0,011 kg reflects the small format suited to routine sample preparation, dissolution, and homogenisation tasks on standard magnetic stirrer plates.
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 45 mm
What is this article?
Rotilabo® magnetic bar with centre ring, cylindric, Ø 8 mm, length 45 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.
