Description
Drying tube with cone NS 14,5/23 bent at an angle of 75° is a compact laboratory drying tube manufactured from borosilicate glass 3.3. The angled geometry facilitates convenient attachment to reaction vessels or gas lines while directing moisture-absorbing media away from the main apparatus path. The NS 14,5/23 cone provides a standard ground-joint interface for secure, interchangeable connection within glassware assemblies. Net weight is only 0,029 kg, rendering the component lightweight and easy to handle during routine setup or dismantling. Offered by manufacturer Rettberg as a single piece, the tube benefits from the chemical inertness and thermal stability of borosilicate glass 3.3, making it appropriate for protecting moisture-sensitive reactions, drying gas streams or serving as a simple guard tube in organic and inorganic laboratory work. Its precise bend angle and joint dimensions support reproducible configurations in teaching, research and analytical environments where reliable exclusion of atmospheric humidity is required.

Questions about Drying tube, cone size 14,5/23, curved with an angle of 75°
What is this article?
Drying tube, cone size 14,5/23, curved with an angle of 75° 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.
