Description
BOLA double-blade stirring shaft, length 800 mm with 10 mm shaft diameter and outer blade dimensions 110×20 mm, is a PTFE-coated stainless steel laboratory stirrer for controlled mixing. It features a PTFE-coated stainless steel shaft fitted with two PTFE stirring blades mounted crosswise and offset by 90°. The upper blade is fastened using clamping screws of PEEK compound. Specified dimensions include a clamping diameter of 8,0 mm, blade spacing of 100 mm, and blade measures A–B–C of 110–20–5 mm. Net weight is 0,47 kg. Offered as 1 piece, the unit is intended for paddle-type stirring where a longer shaft and wider blades are required. PTFE surfaces on shaft and blades provide a chemically resistant working interface around the stainless-steel core. This BOLA model from manufacturer Bohlender is suited to routine laboratory agitation duties that call for defined geometry, secure blade fixing, and fluoropolymer-protected contact parts.

Questions about BOLA Stirrer Shafts with Two Paddles, L 800 mm Ø 10mm aØ 110x20 mm PTFE-coated S
What is this article?
BOLA Stirrer Shafts with Two Paddles, L 800 mm Ø 10mm aØ 110x20 mm PTFE-coated S 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.
