Description
PR 33 propeller stirrer with guide ring (V4A) is a stainless-steel laboratory impeller intended for solutions, emulsions and suspensions in larger vessels. Blade dimensions are optimised for an ideal vessel diameter of 165–330 mm, bottom clearance of 33–66 mm, fill height of 165–330 mm and working volumes from 3.500 to 28,200 ml. Overall length is 400 mm, with an 8 mm diameter stirring shaft that fits standard overhead-stirrer chucks. Constructed from V4A stainless steel, the stirrer delivers mechanical robustness and good chemical resistance for continuous laboratory use. The guide ring assists in stabilising the flow field during axial agitation, promoting uniform mixing throughout the recommended volume range. Offered by manufacturer Heidolph as a single-piece accessory, the PR 33 propeller stirrer integrates readily into preparative and process laboratories. Its net weight of 0,260 kg and compact form factor simplify handling and storage while supporting reliable performance with low- to medium-viscosity media in research and quality-control applications.

Questions about PR 33 Ringed Propeller (V4A)
What is this article?
PR 33 Ringed Propeller (V4A) is the article on this page. Luminix Health distributes Heidolph 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.
