Description
BOLA half-moon stirring blades, 68 x 24 x 3 mm, are laboratory stirrer blades manufactured entirely from polytetrafluoroethylene (PTFE) and equipped with a double groove. The 8,5 mm bore diameter fits stirring shafts for 250 ml round-bottom flasks with NS 29/32 ground joints. Blade dimensions of 68 x 24 x 3 mm provide a half-moon profile suited to thorough mixing in mid-scale laboratory vessels. Full PTFE construction delivers chemical resistance and a low-adhesion surface for work with aggressive reagents in synthesis and sample preparation. These BOLA components from manufacturer Bohlender are supplied in a pack of three pieces for overhead stirring applications that demand corrosion resistance and easy cleaning. The double-groove design aids stable seating on the shaft during prolonged runs. Net weight is 0,008 kg. They are intended for chemical, pharmaceutical, and analytical laboratories needing PTFE half-moon blades matched to 250 ml NS 29/32 flasks and standard 8,5 mm shafts.
This article is part of Stirring shafts, propellers & impellers, in Stirring, shaking & mixing.

Questions about BOLA Moon-Shaped Stirrer Blades, 68x24x3 mm Ø 8,5 mm 250 ml PTFE double long-gro
What is this article?
BOLA Moon-Shaped Stirrer Blades, 68x24x3 mm Ø 8,5 mm 250 ml PTFE double long-gro 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.
