Description
R 1331 anchor stirrer with Ø90 mm blade and 350 mm shaft length is intended for thorough mixing of medium- to high-viscosity fluids. Its anchor profile produces tangential flow and high shear in the peripheral zone, which helps minimise wall deposits and ensures even distribution of solids. Typical uses include polymer reactions and the uniform dispersion of high mineral contents in liquids; the design is optimised for operation at low rotational speeds. Shaft diameter is 8 mm and stirrer diameter is 90 mm. Available from manufacturer IKA as a single-piece accessory, the R 1331 pairs with compatible overhead stirrers for laboratory and process development tasks. The larger blade diameter extends wall-adjacent mixing performance in wider vessels while maintaining stable stirring characteristics. With a net weight of 0,203 kg, the unit offers a robust yet manageable solution for viscous formulations in research, production support and quality-control environments.
This article is part of Stirring shafts, propellers & impellers, in Stirring, shaking & mixing.

Questions about R 1331, Anchor stirrer, Ø90 mm, 350 mm
What is this article?
R 1331, Anchor stirrer, Ø90 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.
