Description
Stirring rod Ø 7–8 mm, length 400 mm is a laboratory stirring shaft equipped with an interchangeable PTFE toggle device for controlled mixing in beakers, flasks and reaction vessels. The rod has a diameter of 7–8 mm and an overall length of 400 mm, providing convenient reach for bench-scale stirring applications. The replaceable PTFE knebel (toggle) attachment allows the stirring geometry to be adapted or renewed without discarding the entire rod, supporting flexible use with different vessel sizes and mixing requirements. Suitable for manual or driven stirring setups in chemistry, biology and general laboratory workflows, the design emphasises chemical resistance at the contact element through the PTFE component. Supplied as a single piece from manufacturer Witeg, this stirring rod is a practical accessory for routine sample preparation, dissolution and homogenisation tasks where a slim 7–8 mm shaft and 400 mm length are preferred. Net weight is 0,043 kg, making it easy to handle and store alongside other overhead or hand-stirring tools.
This article is part of Magnetic stirrers, in Stirring, shaking & mixing.

Questions about Stirrer shafts, 7-8 mm dia., suitable
What is this article?
Stirrer shafts, 7-8 mm dia., suitable is the article on this page. Luminix Health distributes Witeg 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.
