Beschrijving
Stirring blade is a stainless-steel laboratory mixing accessory intended for use with laboratory stirrers R18, R50 and R50D. It combines an overall length of 350 mm with a blade width of 90 mm and a blade height of 15 mm, while the stirring rod has a diameter of 8 mm for secure mounting in compatible chucks. Fabricated from stainless steel, the component offers mechanical strength and corrosion resistance for everyday agitation of aqueous and many organic laboratory media. This stirring blade from manufacturer Marienfeld is well suited to beakers, flasks and open vessels where controlled propeller-style mixing supports dissolution, suspension and homogenisation work. The defined geometry of the 350 mm shaft and 90 mm blade span helps deliver reproducible flow patterns once the drive unit is set. Supplied as a single piece, it fits preparative chemistry, sample preparation and quality-control routines that rely on the named R18, R50 and R50D laboratory stirrers. Dimensions and material selection make it a practical spare or replacement element within standard laboratory stirring setups.

Questions about Blade stirrers,
What is this article?
Blade stirrers, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Stirring shafts, propellers & impellers, inside Stirring, shaking & mixing, in Instrumenten.
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.
