Description
BOLA lower bearing G-MRK, Ø 10 mm NS 29/32 / NS 45/40 is a laboratory spare and accessory part for BOLA magnetic stirrer couplings of the G-MRK type. It is matched to ground joints NS 29/32 or NS 45/40 and accommodates stirrer shafts of 10 mm diameter, corresponding to couplings such as C 502-16 and C 504-16. The bearing is produced from a PTFE-PEEK compound that offers chemical resistance together with the mechanical strength needed for continuous shaft support in magnetic drive assemblies. Net weight is 0,022 kg and the item is supplied as one piece per pack. In use, the lower bearing helps maintain shaft alignment and low-friction guidance inside the coupling housing while preserving the inert polymer contact path typical of BOLA stirring hardware. Manufacturer Bohlender supplies this G-MRK component for laboratories that standardise on NS ground-joint glassware and magnetic stirrer couplings. It is appropriate for synthesis, scale-up trials and general laboratory stirring where a robust 10 mm shaft interface is specified.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about BOLA Lower Bearing G-MRK, Ø 10 mm NS 29/32 NS 45/40 for BOLA Magnetic Stirrer He
What is this article?
BOLA Lower Bearing G-MRK, Ø 10 mm NS 29/32 NS 45/40 for BOLA Magnetic Stirrer He 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.
