Description
BR 11 blade stirrer (V4A) is a stainless-steel impeller suited to solutions, emulsions and suspensions in laboratory vessels. Blade dimensions make it ideal for containers with 100 mm diameter, 5 mm bottom clearance, 100 mm filling height and approximately 800 ml working volume. The stirrer has an overall length of 400 mm. Its stirring shaft measures 8 mm in diameter, and the blade itself is 12 mm long by 50 mm wide. These proportions support efficient mixing and homogenisation for a range of fluid viscosities typical in chemical, pharmaceutical and research applications. Constructed entirely from stainless steel, the BR 11 provides corrosion resistance and mechanical durability for repeated laboratory use. Supplied as one piece from manufacturer Heidolph, the impeller couples readily with standard overhead stirrer motors. Net weight is 0,160 kg. It constitutes a practical choice for routine blending, suspension and emulsion tasks that require a compact blade geometry of defined size.
This article is part of Stirring shafts, propellers & impellers, in Stirring, shaking & mixing.

Questions about BR 11 Straight-Blade Impeller (V4A)
What is this article?
BR 11 Straight-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 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.
