Description
BOLA GT glass stirring shaft with crescent stirrer blade is a precision KPG stirring shaft made from borosilicate glass for laboratory vessels fitted with ground joint NS 29/32. Overall length is 490 mm, with a shaft diameter of 10 mm and a chuck diameter of 8 mm for reliable clamping in laboratory stirrer motors. The tiltable crescent (half-moon) stirrer blade features an angled groove plus fastening bolt; both blade and bolt are produced completely from PTFE and measure 90 × 24 × 3 mm. Because the medium touches only glass and PTFE, the assembly offers universal chemical resistance across a broad range of reagents. This single-piece unit from manufacturer Bohlender has a net weight of 0,07 kg and is intended for surface stirring in flasks and reaction vessels with NS 29/32 joints. The rigid borosilicate glass shaft maintains alignment, while the PTFE blade components resist aggressive solvents, acids and bases. It supports efficient mixing in synthesis, sample preparation and routine laboratory work where metal-free contact is required.

Questions about BOLA GT Glass Stirrer Shafts, L 490 mm Ø 10 mm NS 29/32 GLASS/PTFE moon-shaped s
What is this article?
BOLA GT Glass Stirrer Shafts, L 490 mm Ø 10 mm NS 29/32 GLASS/PTFE moon-shaped s is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Stirring & mixing accessories, inside Stirring, shaking & mixing, in Lab instruments.
Stirring accessories are the bosses, the retort clamps and the spare knobs that hold an overhead stirrer over the vessel. The stand has to carry the motor's mass, not only the flask's.
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.
