Description
Nitrogen tube with core, 250 ml is a laboratory glass vessel intended for inert-gas handling in ground-joint systems. Constructed from DURAN® glass, it incorporates an NS 14/23 standard ground joint together with a stopcock whose borehole measures 2,5 mm for controlled gas flow. The core-equipped configuration supports nitrogen blanketing and protection of contents when used with round flasks and complementary ground-joint glassware. Delivered as one piece weighing 0,431 kg, the 250 ml capacity serves larger preparative and analytical tasks that require a closed glass environment. This nitrogen tube from manufacturer Lenz is aimed at research and routine laboratories that rely on NS 14/23 connections. DURAN® construction provides the chemical resistance and thermal behaviour typical of quality laboratory glassware, while the defined cock borehole enables regulated introduction or maintenance of nitrogen atmospheres. The vessel integrates into existing glass trains for inert-atmosphere procedures, gas-line connections and related laboratory handling without changing joint geometry or compatibility across the apparatus.

Questions about Nitrogen tube, with core, 250 ml, DURAN®, NS 14/23, cock borehole 2.5mm
What is this article?
Nitrogen tube, with core, 250 ml, DURAN®, NS 14/23, cock borehole 2.5mm is the article on this page. Luminix Health distributes Lenz 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.
