Beschreibung
PTFE stirring blades 125 mm provide interchangeable mixing elements for laboratory shafts equipped with a toggle connection. Fabricated from PTFE at a wall thickness of 2,5 mm, each blade has a width of 35 mm and a length of 125 mm, offering an extended surface for efficient liquid agitation. These components are intended for propeller, anchor and turbine stirrer setups commonly used in chemical, pharmaceutical and analytical laboratories. The PTFE material ensures high chemical resistance and minimises sample contamination risk. Available as a single unit, the blades fit standard knebel-style shafts and can be exchanged quickly when different geometries are required. Produced by manufacturer Witeg, they combine dimensional accuracy with the inert properties of PTFE, making them suitable for aqueous, organic and mildly corrosive media. Their defined proportions support stable stirring performance while remaining easy to clean and maintain between experimental runs.

Questions about PTFE-stirrer blade, breadth: 35 mm, le
What is this article?
PTFE-stirrer blade, breadth: 35 mm, le 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 Präzisionsinstrumente.
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.
