Description
Rotilabo® tube stirring magnet is a PTFE-coated magnetic stir bar with a diameter of 20 mm, intended for tube and vessel mixing on laboratory magnetic stirrers where a larger bar diameter improves coupling and mixing action. The Ø 20 mm size suits broader tube formats and small vessels that can accommodate a more substantial stirring element, promoting effective circulation of liquids, buffers and process mixtures under magnetic drive. A full PTFE coating supplies a chemically resistant working surface for many standard laboratory media and helps shield both the magnet core and the vessel interior during prolonged stirring. Delivered as a single unit, it fits neatly into accessory kits for hotplate stirrers and dedicated mixing stations. The product belongs to the Rotilabo® line from manufacturer ROTH SELECTION, aligned with laboratory appliances and magnetic-stirrer accessories. Unit weight is 0,005 kg. Select this diameter when tube or vessel geometry allows a 20 mm coated bar and reliable magnetic coupling is required for routine laboratory agitation tasks.
This article is part of Magnetic stirrers, in Stirring, shaking & mixing.

Questions about Rotilabo® tube stirring magnet, PTFE coated, Ø 20 mm, 1 unit(s)
What is this article?
Rotilabo® tube stirring magnet, PTFE coated, Ø 20 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.
