Description
Propeller stirrer with three blades is a one-piece cast mixing tool designed for reliable agitation in laboratory and process vessels. The impeller measures 650 mm in overall length with a blade diameter of 70 mm and a shaft diameter of 10 mm, giving a robust geometry suited to medium-viscosity media and larger flasks or reactors. Manufactured as a single cast piece, the three-blade propeller delivers consistent torque transmission and mechanical stability during continuous stirring. This configuration from manufacturer Bochem is widely used for homogenisation, suspension and heat-transfer support in chemical synthesis, sample preparation and pilot-scale work. The unit is supplied as 1 pc and integrates readily with standard overhead stirrer drives that accept a 10 mm shaft. Its cast construction supports durable service under typical laboratory loads while the defined blade diameter promotes efficient axial and radial flow. Ideal for routine mixing tasks where a durable three-blade propeller of fixed length and diameter is required.
This article is part of Stirring shafts, propellers & impellers, in Stirring, shaking & mixing.

Questions about Propeller stirrer with 3 blades, 1 casting piecel, L=650mm, D=70mm, shaft d
What is this article?
Propeller stirrer with 3 blades, 1 casting piecel, L=650mm, D=70mm, shaft d is the article on this page. Luminix Health distributes Bochem for laboratory use. It sits in Stirring shafts, propellers & impellers, inside Stirring, shaking & mixing, in Lab instruments.
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.
