Description
BOLA clamping nut SG-MRK is a precision laboratory accessory designed for secure fastening on BOLA magnetic stirrer couplings SG-MRK with ground joint NS 19/26 and shaft diameter 6 mm. Manufactured from PTFE-mica, the nut combines chemical resistance with reliable mechanical grip in demanding stirring applications. It is intended for use with the corresponding SG-MRK C coupling series and supports stable shaft retention during continuous laboratory agitation. Supplied as a pack of three pieces from manufacturer Bohlender, the component suits routine assembly and maintenance of magnetic stirrer drive systems in chemical synthesis, process development and analytical work. The compact design integrates cleanly with standard NS 19/26 glassware interfaces, helping maintain alignment and sealing integrity around the stirrer shaft. With a net weight of only 0,0045 kg per unit, the clamping nut adds minimal mass while providing dependable clamping force. This spare or replacement part is well suited to laboratories that operate BOLA SG-MRK magnetic stirrer couplings and require chemically inert fastening hardware for shafts of 6 mm diameter.

Questions about BOLA Clamping Nut SG-MRK, Ø 6 mm NS 19/26 for BOLA Magnetic Stirrer Heads (SG-MR
What is this article?
BOLA Clamping Nut SG-MRK, Ø 6 mm NS 19/26 for BOLA Magnetic Stirrer Heads (SG-MR 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.
