Description
Nitrogen tubes with stopcock, DURAN® provide a practical glass vessel for nitrogen handling and inert-atmosphere laboratory work. Constructed from DURAN® glass, each unit incorporates a stopcock and a ground-glass cone NS 14/23 for reliable connection to standard jointed glassware. The 50 ml capacity is well suited to intermediate-scale transfers, temporary holding of gases or liquids, and routine synthetic or analytical procedures that require isolation from air. Offered as one piece with a weight of 0,083 kg, the tube fits neatly into common laboratory setups built around NS joints. These nitrogen tubes from manufacturer Lenz form part of the range of round flasks and flasks with ground glass joints used across research, quality-control and teaching environments. DURAN® material, integrated stopcock control and the NS 14/23 cone together deliver a straightforward, reusable component for everyday gas-handling and inert-gas techniques without added complexity.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Nitrogen tubes with stopcock, DURAN®, with stopcock, cone NS 14/23, 50 ml
What is this article?
Nitrogen tubes with stopcock, DURAN®, with stopcock, cone NS 14/23, 50 ml is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Matériel de laboratoire.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
