Description
Modified bubble counter with core NS 14,5/23 is a laboratory glassware component designed for direct mounting on apparatus. Fabricated from borosilicate glass 3.3, it includes a GL 25 thread that permits straightforward filling with oil to enable clear visual monitoring of gas bubbles. The NS 14,5/23 core joint ensures secure compatibility with standard conical ground-joint assemblies used throughout chemical and process laboratories. With a net weight of 0,098 kg the unit remains lightweight yet robust enough for routine experimental handling. This modified design from manufacturer Rettberg supports reliable observation of gas evolution, flow indication or reaction progress in organic synthesis, distillation and inert-atmosphere work. The chemical resistance and thermal stability of borosilicate glass 3.3 allow repeated use under typical laboratory conditions without degradation. Integration of the oil reservoir via the GL 25 thread eliminates the need for separate fittings, simplifying setup and improving visibility of bubble rates. Suitable for research, analytical and pilot-scale applications, the bubble counter contributes to controlled and safe gas-handling workflows wherever visual confirmation of flow is required.

Questions about Bubble counter, modified, cone size 14,5/23
What is this article?
Bubble counter, modified, cone size 14,5/23 is the article on this page. Luminix Health distributes Rettberg 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.
