Description
Rotilabo® magnetic bar with centre ring is a cylindric stirring bar designed for reliable mixing on laboratory magnetic stirrers. With a diameter of 4,5 mm and a length of 12 mm, this compact accessory suits small vessels and low-volume work where controlled agitation is required. The centre ring helps the bar maintain a stable spinning position and reduces unwanted tumbling during continuous operation. Supplied as a single piece and weighing 0,010 kg, it is a practical spare or replacement for everyday lab setups. This Rotilabo® item from manufacturer ROTH SELECTION fits the standard range of accessories for magnetic stirrers used in chemistry, biology, and general analytical workflows. Its cylindric geometry supports smooth rotation in flasks, beakers, and similar containers when paired with a compatible drive unit. Choose this format when a short, narrow bar is preferred for tight spaces or modest sample volumes. The product is intended for laboratory appliance use within magnetic stirring applications and related labware configurations.

Questions about Magnetic bars ROTILABO® with centre ring, , 4.5 mm, 12 mm, 1 unit(s)
What is this article?
Magnetic bars ROTILABO® with centre ring, , 4.5 mm, 12 mm, 1 unit(s) 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.
