Description
BOLA half-moon stirring blades are laboratory mixing blades made completely from polytetrafluoroethylene (PTFE), equipped with a single groove and a 10 mm bore for attachment to a stirring shaft. Blade dimensions are 50 x 24 x 3 mm, designed for 100 ml ground-joint round-bottom flasks with NS 29/32 necks. The half-moon shape supports effective agitation in small flask volumes while keeping the wetted blade material fully PTFE for chemical resistance and easy cleaning. These components fit typical overhead-stirrer workflows associated with wing, anchor and turbine stirrer categories, serving as the PTFE blade element rather than a full drive system. Offered as a pack of 2 pc(s) with a net weight of 0,005 kg per item data, they suit laboratories that prefer spare blades on hand for 100 ml NS 29/32 setups. Produced by Bohlender, the specification centres on single-groove mounting, a 10 mm bore and blade proportions suited to NS 29/32 round flasks. Appropriate for research, process-development and teaching environments needing PTFE half-moon blades matched to 100 ml vessels and standard ground-joint glassware.

Questions about BOLA Moon-Shaped Stirrer Blades, 50x24x3 mm Ø 10 mm 100 ml PTFE, with long-groov
What is this article?
BOLA Moon-Shaped Stirrer Blades, 50x24x3 mm Ø 10 mm 100 ml PTFE, with long-groov 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.
