Description
Rotilabo® stirring magnets with centre ring are magnetic stir bars for everyday laboratory mixing. This red model has a diameter of 8 mm and a length of 38 mm, dimensions suited to medium flasks, beakers and reaction vessels used on magnetic stirrers. The centre-ring geometry helps keep the bar aligned during rotation and limits unnecessary contact with the vessel base. Supplied as 1 pc with a unit weight of 0,012 kg, it is easy to handle, store and replace among other labware accessories. These accessories for magnetic stirrers from manufacturer ROTH SELECTION support routine sample preparation, dissolution work and general wet-chemistry workflows in research, analytical and teaching laboratories. The distinctive red colour aids quick visual identification when several stir bars of different sizes are kept together. Suitable for homogenising solutions, maintaining suspensions and continuous agitation in standard glass or plastic containers, the bar integrates into conventional magnetic stirring setups without extra adapters. Laboratories needing a longer centre-ring stirring magnet for medium-volume applications will find this format a practical match for daily protocols.
This article is part of Magnetic stirrers, in Stirring, shaking & mixing.

Questions about Rotilabo®-stirring magnets, centre ring, red, Ø 8 mm, length 38 mm, 1 unit(s)
What is this article?
Rotilabo®-stirring magnets, centre ring, red, Ø 8 mm, length 38 mm, 1 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Magnetic stirrers, inside Stirring, shaking & mixing, in Lab instruments.
A magnetic stirrer is the motor and the plate under the flask. Many also heat. The stirring capacity is the litres of a water-like liquid it can turn, and a viscous liquid defeats a rating that was measured on water.
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.
