Description
BOLA Magnetic stirrer coupling (P-MRK) with NS 29/32 ground joint and 10 mm shaft diameter is designed for PTFE-jacketed BOLA stirring shafts. It consists of an encapsulated stainless-steel drive bell with ball bearings, a rotor and lower bearing made of PEEK compound, and a borosilicate-glass shaft receiver. The compact form factor minimises bench and apparatus space. A pore-free, fully welded rotor eliminates leakage routes and memory effects. A PEEK-compound clamping screw holds the stirring shaft firmly and transmits torque effectively. The ground-joint core is fitted with a PTFE Combi nut (Safe-Lab) that secures the conical joint and simplifies disconnection. A square drive of 6 mm wrench size accepts the overhead stirrer or a further coupling. Specified dimensions include height 145 mm, maximum shaft insertion length 95 mm, and drive-bell outer diameter 50 mm. Listed material is polytetrafluoroethylene (PTFE). Supplied as a single piece weighing 0,784 kg net, this Bohlender magnetic coupling provides a sealed, space-efficient link between laboratory stirrer drives and compatible 10 mm shafts on NS 29/32 glassware.

Questions about BOLA Magnetic Stirrer Heads (P-MRK), NS 29/32, Ø 10 mm consisting of: Driving b
What is this article?
BOLA Magnetic Stirrer Heads (P-MRK), NS 29/32, Ø 10 mm consisting of: Driving b is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Stirring & mixing accessories, inside Stirring, shaking & mixing, in Lab instruments.
Stirring accessories are the bosses, the retort clamps and the spare knobs that hold an overhead stirrer over the vessel. The stand has to carry the motor's mass, not only the flask's.
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.
