Description
R 2311 paddle stirrer with 150 mm diameter is a laboratory mixing accessory engineered for tangential flow with low turbulence. The 800 mm shaft length and 13 mm shaft diameter support stable operation at low to medium speeds, enabling good heat exchange and gentle treatment of the product. This geometry suits processes where shear-sensitive media must be blended carefully while still achieving effective circulation in the vessel. Pack size is 1 pc; net weight is 1,107 kg and gross weight 1,240 kg. The paddle design promotes a predominantly tangential flow pattern that limits unwanted turbulence and supports uniform temperature distribution during mixing. From manufacturer IKA, the R 2311 is a practical accessory for overhead stirrers used in research, development and quality-control laboratories. Defined dimensions make it straightforward to match to vessels that accommodate an 800 mm immersion length and a 150 mm paddle span. It is intended for controlled mixing tasks that benefit from moderate speed ranges and gentle product handling rather than high-shear dispersion.
This article is part of Overhead stirrers, in Stirring, shaking & mixing.

Questions about R 2311, Paddle stirrer, Ø150, 800 mm
What is this article?
R 2311, Paddle stirrer, Ø150, 800 mm is the article on this page. Luminix Health distributes IKA for laboratory use. It sits in Overhead stirrers, inside Stirring, shaking & mixing, in Instruments de laboratoire.
An overhead stirrer drives a shaft from above, for volumes and viscosities a magnetic bar cannot move. Torque and speed range are the ratings. The chuck and the stand are part of using it. A high-speed disperser is a different head.
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.
