Description
Nitrogen tubes with stopcock, DURAN® are compact laboratory glass vessels fitted with an integrated stopcock and a cone NS 14/23 ground joint. The 10 ml capacity is suited to small-scale nitrogen handling, purge steps, and jointed micro-assemblies where a male NS 14/23 cone is required. Manufactured in DURAN® glass, the tube belongs with laboratory glass, vessels, and consumables—specifically round flasks and flasks with ground glass joints. Pack size is 1 pc, and the weight is 0,048 kg, keeping the piece light for delicate setups and standard racks. This nitrogen tube with stopcock from manufacturer Lenz uses the cone NS 14/23 format so it can seat directly into matching sockets on adapters, manifolds, or receiving vessels. The stopcock enables controlled opening and closing of the gas path without breaking the joint connection, supporting brief blanketing or isolation during sample work. Explicit listing of capacity, cone joint size, and stopcock configuration aids method documentation and reordering in multi-user laboratories. The small 10 ml format complements larger socket-style nitrogen tubes when only limited volume is needed at the NS 14/23 interface.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Nitrogen tubes with stopcock, DURAN®, with stopcock, cone NS 14/23, 10 ml
What is this article?
Nitrogen tubes with stopcock, DURAN®, with stopcock, cone NS 14/23, 10 ml is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
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.
