Description
Rotilabo®-dumbell magnetic stirring rods are magnetic stir bars in a dumbbell profile with a diameter of 8 mm and a length of 35 mm. The dumbbell geometry promotes stable coupling to magnetic stirrers and efficient mixing in small to medium vessels, flasks, and beakers. An outer diameter of 8 mm and overall length of 35 mm suit tubes, vials, and compact reaction vessels commonly used on laboratory magnetic stirrers. Each unit is supplied as 1 pc with a weight of about 0,017 kg, convenient for individual replacement or accessory kits. These stirring rods from manufacturer ROTH SELECTION serve as accessories for magnetic stirrers in chemical synthesis, sample preparation, and dissolution work. The dumbbell shape helps maintain centered rotation and reduces spin-out at moderate speeds. Laboratories equipping stirrer plates for routine mixing can specify this 8 mm × 35 mm Rotilabo® dumbbell rod when a compact, well-defined stir bar is required for reproducible agitation in everyday bench protocols.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about Rotilabo®-dumbell magnetic stirring rods, Ø 8 mm, length 35 mm, 1 unit(s)
What is this article?
Rotilabo®-dumbell magnetic stirring rods, Ø 8 mm, length 35 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.
