Description
BOLA four-bladed propeller stirrer shafts with a length of 350 mm and a shaft diameter of 8 mm are robust laboratory mixing tools for chemically aggressive media. The stainless steel shaft is PTFE-coated and the propeller is manufactured entirely from PTFE, featuring four angular blades inclined at 45°. Medium contact is limited to PTFE, which provides universal chemical resistance. Outer stirring diameter is 50 mm, with blade dimensions 50 mm × 18 mm × 4 mm according to the manufacturer drawing. Chuck diameter is 6,5 mm for secure drive coupling. Material is polytetrafluoroethylene (PTFE) on the wetted parts; net weight is 0,1248 kg. Offered as a single piece from manufacturer Bohlender, this four-bladed design supports thorough mixing in larger laboratory vessels and reaction systems used in chemical synthesis, process development and materials research where inert surfaces and a well-defined propeller geometry are required.
This article is part of Stirring shafts, propellers & impellers, in Stirring, shaking & mixing.

Questions about BOLA Propeller-Stirrer Shafts with 4 Blades, L 350 mm Ø 8 mm aØ 50 mm Fluoroplas
What is this article?
BOLA Propeller-Stirrer Shafts with 4 Blades, L 350 mm Ø 8 mm aØ 50 mm Fluoroplas 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.
