Description
BOLA retaining ring G-MRK, Ø 8+10 mm NS 29/32 / NS 45/40 is a laboratory spare part designed for BOLA magnetic stirrer couplings of the G-MRK series. It suits couplings with ground joint NS 29/32 or NS 45/40 for shaft diameters of 8 mm as well as 10 mm, securing the assembly during stirring work. Manufactured from PTFE-GF, the ring combines chemical resistance with the mechanical stability needed in glassware setups. Each pack contains 5 pieces, supporting routine maintenance and replacement in research and process laboratories. With a net weight of 0,001 kg per unit context, the component remains lightweight yet functional at the ground-joint interface. This retaining ring from manufacturer Bohlender is intended specifically for matching BOLA G-MRK magnetic stirrer couplings and helps keep shafts correctly positioned under magnetic drive. Suitable for labware configurations that rely on standard conical ground joints, it integrates into existing BOLA stirring systems without altering the coupling geometry. Ideal for laboratories that standardise on BOLA G-MRK hardware and require reliable PTFE-GF retaining accessories in multi-piece packs.

Questions about BOLA Locking Ring G-MRK, Ø 8+10 mm NS 29/32 / NS 45/40 for BOLA Magnetic Stirrer
What is this article?
BOLA Locking Ring G-MRK, Ø 8+10 mm NS 29/32 / NS 45/40 for BOLA Magnetic Stirrer is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
