Description
PTFE Stirring Impeller 70 mm is a laboratory stirring component made of PTFE with a blade width of 10 mm, a length of 70 mm and a wall thickness of 2,5 mm. This impeller from manufacturer Witeg is suitable for paddle, anchor and turbine stirrer assemblies commonly employed in chemical and pharmaceutical laboratories. The intermediate length provides effective mixing in standard reaction vessels while the PTFE material ensures chemical inertness toward aggressive reagents. Offered as a single piece with net and gross weight of 0,013 kg, the impeller delivers mechanical stability through its defined wall thickness and supports both routine and specialised agitation tasks. It is a practical accessory for research, synthesis and quality-control workflows that require durable, chemically resistant stirring elements of precise dimensions.
This article is part of Stirring shafts, propellers & impellers, in Stirring, shaking & mixing.

Questions about COLLABSIBLE PTFE PADDLES, BREADTH: 10 MM
What is this article?
COLLABSIBLE PTFE PADDLES, BREADTH: 10 MM is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Stirring shafts, propellers & impellers, inside Stirring, shaking & mixing, in Instruments de laboratoire.
A shaft, a propeller or an impeller is the wetted end of an overhead stirrer. The diameter and the pitch decide whether the liquid turns over. The material, stainless steel or PTFE, decides what the liquid may be. The chuck size has to match the stirrer.
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.
