Description
Test tube NS 19/26 is a laboratory test tube with a standard ground joint NS 19/26, an outer diameter of 22 mm and a length of 150 mm. It is intended for routine sample work, small-scale reactions and general laboratory tasks that require a robust conical joint interface. The NS 19/26 joint connects to matching stoppers, adapters and other jointed glassware, enabling modular assembly of simple apparatus. Supplied as a single unit and weighing 0,050 kg, the tube suits individual replacement or completion of existing glassware sets. This test tube from manufacturer ROTH SELECTION is part of the laboratory glass, vessels and consumables range employed in analytical, teaching and research settings. Clear definition of joint size, diameter and length simplifies selection for distillation setups, reflux arrangements or temporary sample containment under jointed closures. Laboratories that work with NS joints benefit from direct interchangeability with complementary components already in everyday use.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Test tube, NS 19/26, Ø 22 mm, L 150 mm, 1 unit(s)
What is this article?
Test tube, NS 19/26, Ø 22 mm, L 150 mm, 1 unit(s) is the article on this page. Luminix Health distributes Carl Roth 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.
