Description
BOLA half-moon stirring blades provide PTFE mixing elements tailored to larger laboratory round-bottom flasks. Blade dimensions are 125 × 24 × 3 mm, with a single groove and a 10 mm bore diameter for reliable attachment to a stirrer shaft of corresponding size. The design is matched to 4,000 ml and 6,000 ml ground-joint round flasks with NS 29/32 joints, supporting effective half-moon agitation across higher working volumes. Constructed completely from polytetrafluoroethylene (PTFE), the blades combine chemical inertness with a smooth, non-stick surface suited to demanding organic, inorganic and aqueous media. Offered as two pieces per pack from manufacturer Bohlender, each unit has a net weight of 0,015 kg and fits standard overhead stirring assemblies used in synthesis, scale-up trials and preparative work. The elongated half-moon profile promotes circulation along the flask wall while remaining compatible with conventional NS 29/32 glassware and laboratory drive systems in research and industrial laboratory environments.
This article is part of Stirring shafts, propellers & impellers, in Stirring, shaking & mixing.

Questions about BOLA Moon-Shaped Stirrer Blades, 125x24x3mm Ø 10mm 4000/6000ml PTFE, with long-g
What is this article?
BOLA Moon-Shaped Stirrer Blades, 125x24x3mm Ø 10mm 4000/6000ml PTFE, with long-g is the article on this page. Luminix Health distributes Bohlender 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.
