Description
R 1381 propeller stirrer is a three-bladed laboratory stirring element featuring a flow-optimised shape for effective mixing with low shear. With a stirrer diameter of 45 mm, shaft length of 350 mm and shaft diameter of 8 mm, it draws the medium from above and below, supporting uniform circulation at medium to high speeds. The compact blade geometry is well suited to vessels where controlled propeller action and reduced mechanical stress on samples are important. Suitable for chemical, biotechnological and general laboratory applications, this accessory integrates with compatible overhead stirrer drives. Supplied as one piece from manufacturer IKA, the R 1381 offers defined dimensions and reliable handling for everyday agitation tasks. Net weight is 0,164 kg (gross 0,242 kg). Its streamlined three-blade design makes it a practical choice for reproducible mixing performance across a range of viscosities and process scales.
This article is part of Stirring shafts, propellers & impellers, in Stirring, shaking & mixing.

Questions about R 1381, Propeller stirrer, 3-bladed, Ø45 mm, 350 mm
What is this article?
R 1381, Propeller stirrer, 3-bladed, Ø45 mm, 350 mm is the article on this page. Luminix Health distributes IKA 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.
