Description
BOLA Micro paddle stirrer shaft, length 120 mm, is a compact laboratory stirring component with a PTFE-coated stainless steel shaft and a stirring blade made entirely of PTFE. The blade has four wings rounded on the underside, with wing dimensions A–B of 8 mm by 8 mm. Shaft diameter is 3,5 mm and chucking diameter is 2,5 mm, supporting secure mounting in standard laboratory stirrer chucks for micro-scale work. Universal chemical resistance is obtained because the process medium contacts only PTFE, so the stainless steel core remains isolated from aggressive reagents and solvents. This micro paddle design from manufacturer Bohlender suits propeller-style agitation in small vessels where inert wetted surfaces and reliable mechanical strength are required. Material performance centres on polytetrafluoroethylene for the blade and coating, combining fluoropolymer inertness with the stability of a steel shaft. The unit is supplied as 1 pc with a net weight of 0,0064 kg and is intended for research, analytical and process-development laboratories that need corrosion-resistant stirring hardware at compact dimensions for controlled mixing of small liquid volumes.
This article is part of Overhead stirrers, in Stirring, shaking & mixing.

Questions about BOLA Micro Surface Stirrer Shafts, L 120 mm, Ø 3,5 mm, aØ 8 mm Fluoroplastic-jac
What is this article?
BOLA Micro Surface Stirrer Shafts, L 120 mm, Ø 3,5 mm, aØ 8 mm Fluoroplastic-jac is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Overhead stirrers, inside Stirring, shaking & mixing, in Lab instruments.
An overhead stirrer drives a shaft from above, for volumes and viscosities a magnetic bar cannot move. Torque and speed range are the ratings. The chuck and the stand are part of using it. A high-speed disperser is a different head.
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.
