Description
Rotilabo® tube stirring magnet is a PTFE-coated magnetic stir bar with a diameter of 9 mm, designed for controlled mixing inside tubes and other narrow laboratory vessels on magnetic stirrers. The compact Ø 9 mm profile suits small-volume work where a full-size bar would be impractical, supporting gentle to moderate agitation of reagents, buffers and sample suspensions. A continuous PTFE coating provides a chemically resistant contact surface toward many common laboratory media while helping protect the vessel wall during rotation. Supplied as a single unit, this accessory is straightforward to stock beside stirrer hotplates and tube racks. The magnet comes from manufacturer ROTH SELECTION within the Rotilabo® range of laboratory appliances and stirrer accessories. With a unit weight of 0,019 kg, it is easy to handle and store. Use it for routine tube-scale mixing in analytical, preparative and teaching laboratories that require a small, coated stirring element matched to confined geometries and everyday magnetic-drive setups.
This article belongs on Magnetic stirrers, in Stirring, shaking & mixing.

Questions about Rotilabo® tube stirring magnet, PTFE coated, Ø 9 mm, 1 unit(s)
What is this article?
Rotilabo® tube stirring magnet, PTFE coated, Ø 9 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.
