Description
Propeller stirrer with four vertical blades in 18/10 steel is a durable laboratory impeller for overhead stirring of liquid media. Overall length is 500 mm with a blade diameter of 50 mm and a shaft diameter of 8 mm, giving a compact geometry suited to beakers, flasks and open process vessels. The four-blade vertical propeller promotes controlled axial flow for homogenisation, suspension and dissolution work in chemical, pharmaceutical and life-science laboratories. Fabricated from corrosion-resistant 18/10 stainless steel (Edelstahl), the stirrer offers a robust metal contact surface for aqueous systems and many routine organic media. Net weight is 0,22 kg (222,0 g), supplied as one piece. This design from manufacturer Bochem couples readily to standard overhead stirrer drives and supports everyday sample preparation, reagent blending and scale-up trials where a stainless-steel propeller is preferred to glass or polymer alternatives. Vertical blade orientation helps limit splashing at moderate speeds while maintaining effective mixing. Ideal as a dedicated blade stirrer for general laboratory agitation tasks requiring dimensional clarity and reliable steel construction.

Questions about Propeller stirrer 4 blades, 18/10, L=500mm, D=50mm
What is this article?
Propeller stirrer 4 blades, 18/10, L=500mm, D=50mm 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.
