Description
BOLA Propeller Stirrer Shaft, length 350 mm, shaft diameter 8 mm and outer diameter 75 mm, is a laboratory propeller stirrer built around a PTFE-coated stainless steel shaft with a propeller made entirely of PTFE. Three blades inclined at 45° in round or angular form define the stirring geometry, while the process medium contacts only PTFE, giving universal chemical resistance. Blade dimensions A–B–C are 75 mm, 18 mm and 3,0 mm, and the clamping diameter is 6,5 mm. Supplied as one piece, this BOLA shaft from manufacturer Bohlender pairs the mechanical support of the coated steel core with inert PTFE surfaces on all wetted parts. Net weight is 0,12 kg; gross weight is 0,17 kg. The 350 mm length and 75 mm propeller span suit standard laboratory vessels where aggressive media must not meet bare metal. Material specification is polytetrafluoroethylene (PTFE) for the propeller and coating, supporting reliable agitation in chemical and research environments that demand chemically resistant stirring equipment.

Questions about BOLA Propeller Stirrer Shafts, L 350 mm Ø 8 mm aØ 75 mm PTFE-coated STAINLESS ST
What is this article?
BOLA Propeller Stirrer Shafts, L 350 mm Ø 8 mm aØ 75 mm PTFE-coated STAINLESS ST 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.
