Description
LR 5000.11 anchor stirrer is a laboratory stirring accessory designed specifically for use in the LR-5.ST laboratory reactor. It is particularly suited to the reliable mixing of viscous materials where conventional impellers may be less effective. Product-contacting components are manufactured from AISI 316 L stainless steel, offering corrosion resistance and durability in demanding laboratory environments. When working with media that tend to adhere to the reactor wall, the related anchor stirrer with scrapers (LR 5000.10) is recommended as an alternative. This accessory from manufacturer IKA integrates cleanly into the LR-5.ST reactor system for controlled agitation tasks. Supplied as one piece, the LR 5000.11 supports research and process development applications that require consistent stirring of high-viscosity samples and formulations. The stirrer geometry promotes thorough homogenisation of thick pastes, gels and polymer-containing mixtures commonly handled in closed reactor setups for synthesis, formulation and scale-up studies.
This article is part of Stirring shafts, propellers & impellers, in Stirring, shaking & mixing.

Questions about LR 5000.11, Anchor stirrer
What is this article?
LR 5000.11, Anchor stirrer 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 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.
