Description
BOLA four-bladed propeller stirrer shaft, length 800 mm with shaft diameter 10 mm and outer propeller diameter 140 mm, is a long-reach PTFE-coated stirrer for larger laboratory vessels and higher-volume mixing. The stainless steel shaft is fully PTFE-coated, and the propeller is produced entirely from PTFE with four angular blades inclined at 45°. Blade dimensions A–B–C are 140 – 22 – 6 mm, giving a broader sweep than smaller variants, while the chuck diameter remains 8,0 mm for standard drive coupling. Contact with the medium is limited to PTFE, ensuring universal chemical resistance. Net weight is 0,473 kg. This single-piece unit from manufacturer Bohlender is designed for demanding laboratory stirring where inert surfaces and strong circulation are essential. The larger four-bladed propeller promotes efficient bulk movement of liquids during dissolution, suspension maintenance and preparative reactions, and the extended 800 mm length accommodates deep reactors or tall flasks without exposing unprotected metal to corrosive or high-purity media.

Questions about BOLA Propeller-Stirrer Shafts with 4 Blades, L 800 mm Ø 10 mm aØ 140 mm Fluoropl
What is this article?
BOLA Propeller-Stirrer Shafts with 4 Blades, L 800 mm Ø 10 mm aØ 140 mm Fluoropl 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.
