Description
Nitrogen tubes with stopcock, DURAN® are laboratory glass vessels fitted with an integrated stopcock and a socket NS 14/23 ground joint. The 50 ml capacity suits compact bench setups where controlled gas access and a standardised joint connection are required. Built in DURAN® glass, the tube is intended for routine laboratory glassware use among round flasks and flasks with ground glass joints. Pack size is 1 pc, and the stated weight is 0,083 kg, so the piece remains easy to handle in jointed assemblies. This nitrogen tube with stopcock from manufacturer Lenz follows the NS 14/23 socket format commonly paired with adapters, gas lines, and complementary ground-joint components. The stopcock allows the interior path to be opened or closed without removing the vessel from the setup, supporting nitrogen handling and related gas-control steps during preparation or temporary holding. Clear specification of capacity, joint type, and stopcock configuration helps method sheets and inventory records stay consistent across multi-user laboratories. The item sits within laboratory glass, vessels, and consumables for everyday synthetic and analytical workflows that call for a stopcock-equipped nitrogen tube in the 50 ml class.
This article belongs on Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Nitrogen tubes with stopcock, DURAN®, with stopcock, socket NS 14/23, 50 ml
What is this article?
Nitrogen tubes with stopcock, DURAN®, with stopcock, socket 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 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.
