Description
PR 30 propeller stirrer (V4A) is a stainless-steel laboratory impeller engineered for thorough mixing of solutions, emulsions and suspensions. With a total length of 400 mm and a stirring shaft diameter of 8 mm, it is optimised for vessels offering an ideal diameter of 145–290 mm, bottom clearance of 29–58 mm, fill height of 145–290 mm and working volumes from 2.400 to 19,200 ml. The blade geometry promotes efficient axial flow and supports homogeneous results across a practical range of liquid formulations. Produced by manufacturer Heidolph, the PR 30 is fabricated from V4A stainless steel for corrosion resistance and mechanical stability in everyday laboratory use. Supplied as one piece, it pairs readily with compatible overhead stirrer drives. Researchers and process chemists rely on its consistent performance when preparing media, reagents or process intermediates. The balanced reach and rigidity make it a practical choice for medium- to large-scale mixing tasks in analytical, quality-control and preparative workflows.

Questions about PR 30 Pitched-Blade Impeller (V4A)
What is this article?
PR 30 Pitched-Blade Impeller (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.
