Description
BOLA blade stirrer shafts with a working length of 600 mm and a shaft diameter of 8 mm are equipped with a straight stirring blade made entirely of PTFE. Blade outer dimensions are 90 x 20 mm with a thickness of 5 mm, while the clamping diameter is 6,5 mm. The stainless steel shaft is fully PTFE-coated so that the process medium contacts only polytetrafluoroethylene, giving universal chemical resistance in aggressive laboratory and process media. Net weight is 0,217 kg. This construction combines the mechanical strength of a steel core with an inert PTFE surface, making the shaft suitable for overhead stirring where metal contact must be avoided. The design supports reliable mixing of corrosive liquids, suspensions and reaction mixtures in glass and plastic vessels. These BOLA stirrer shafts from manufacturer Bohlender are supplied as single pieces and integrate with standard laboratory stirrer drives that accept the stated clamping diameter. Material selection and geometry are intended for routine chemical work requiring inert wetted parts and stable torque transmission along the coated shaft.
This article is part of Stirring shafts, propellers & impellers, in Stirring, shaking & mixing.

Questions about BOLA Stirrer Shafts with Blade, L 600 mm Ø 8 mm aØ 90x20 mm PTFE-coated STAINLES
What is this article?
BOLA Stirrer Shafts with Blade, L 600 mm Ø 8 mm aØ 90x20 mm PTFE-coated STAINLES 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.
