Description
BOLA grid stirring shafts with a length of 450 mm feature a PTFE-coated stainless steel shaft and a grid stirrer made entirely of polytetrafluoroethylene (PTFE). The shaft diameter is 8 mm, the outer diameter is 38 mm, and blade dimensions according to the manufacturer illustration are 38–45 mm. Clamping diameter is 6,5 mm, and the design is intended for ground joint NS 45/40. Pack size is one piece, with a net weight of 0,165 kg. This laboratory stirring component is used for mixing work in glassware systems where PTFE contact surfaces and a coated metal core are required. Dimensions support integration into vessels fitted with the stated standard joint. The shaft belongs to the BOLA range from manufacturer Bohlender and is intended for overhead stirring assemblies in chemical and analytical laboratories. PTFE construction of the grid element addresses chemical resistance needs for many routine reagents, while the coated stainless-steel core provides the structural length of 450 mm. Application contexts include paddle, anchor and turbine stirrer setups in research and process laboratories. All stated lengths, diameters and joint sizes follow the manufacturer data for consistent laboratory handling and fit.

Questions about BOLA Fan-Shaped Stirrer Shafts, L 450 mm Ø 8 mm aØ 38 mm PTFE-coated STAINLESS S
What is this article?
BOLA Fan-Shaped Stirrer Shafts, L 450 mm Ø 8 mm aØ 38 mm PTFE-coated STAINLESS S 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.
