Description
Rotilabo® magnetic bar with centre ring is a cylindric stirring bar designed as an accessory for magnetic stirrers in everyday laboratory work. The bar measures Ø 8 mm in diameter and 50 mm in length, giving a compact geometry suited to smaller vessels and moderate mixing volumes. A centre ring helps the bar maintain a stable spinning position and reduces the tendency to drift or flip during stirring. This single-piece unit is intended for laboratory appliances where reliable magnetic coupling and smooth rotation are required for dissolving, suspending or homogenising samples. The Rotilabo® magnetic bar with centre ring from manufacturer ROTH SELECTION belongs to the standard accessories range for magnetic stirrers and supports routine mixing tasks across chemical, analytical and life-science benches. Cylindric form and defined dimensions allow predictable performance in flasks and beakers matched to the 50 mm length. It is a practical choice whenever a centre-ring magnetic stirring bar of this size is specified for controlled laboratory agitation.
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 50 mm
What is this article?
Rotilabo® magnetic bar with centre ring, cylindric, Ø 8 mm, length 50 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.
