Description
Double-chamber gas bubble counter with cone and socket NS 19/26 is a precision laboratory glassware item for visual monitoring of gas flow in chemical apparatus. Fabricated from borosilicate glass 3.3, it incorporates a double-chamber design with built-in backflow protection and is intended for vertical installation. The unit supports operation under both overpressure and underpressure, giving flexibility across a wide range of experimental setups. Standard ground joint NS 19/26 ensures reliable, leak-resistant coupling to matching glassware. Supplied as a single piece with a net weight of 0,100 kg, this bubble counter from manufacturer Rettberg carries the Rettberg ® mark and is well suited to organic synthesis lines, gas-generation trains and analytical workflows where continuous visual confirmation of gas passage is required. Borosilicate glass 3.3 provides high chemical resistance and thermal stability against typical laboratory reagents and temperature cycles. The compact form factor integrates cleanly into existing vacuum or pressure manifolds while the integrated backflow safeguard reduces the risk of liquid ingress into upstream lines.

Questions about Double-chamber gas bubble counter, cone and socket NS 19/26
What is this article?
Double-chamber gas bubble counter, cone and socket NS 19/26 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.
