Description
BOLA micro paddle stirrer shaft is a compact laboratory stirrer with a PTFE-coated stainless steel shaft and a stirring blade made entirely of PTFE. Four blades rounded on the underside provide gentle yet efficient mixing in small volumes, while the medium contacts only PTFE for universal chemical resistance. Length is 200 mm, shaft diameter 4,0 mm, chuck diameter 3,0 mm, and blade outline 16 mm × 16 mm. Net weight is 0,0146 kg. Offered as one piece, the micro shaft fits precision chucks and is suited to microreactors, small flasks, and analytical sample vessels where space is limited and inert wetted surfaces are required. The construction from manufacturer Bohlender pairs a slender steel core with a full PTFE paddle, supporting controlled agitation in synthesis screening, dissolution tests, and fine-chemical work. Rounded lower edges help reduce shear at the vessel base while maintaining stable rotation at laboratory drive speeds.
This article is part of Overhead stirrers, in Stirring, shaking & mixing.

Questions about BOLA Micro Surface Stirrer Shafts, L 200 mm, Ø 4 mm, aØ 16 mm Fluoroplastic-jack
What is this article?
BOLA Micro Surface Stirrer Shafts, L 200 mm, Ø 4 mm, aØ 16 mm Fluoroplastic-jack 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.
