Description
Inlet tubes NS 14/23 are specialised laboratory glassware components intended for the controlled introduction of gases into reaction vessels and apparatus. They incorporate a standard ground joint of NS 14/23 together with a right-angled bent olive and an integrated valve stopcock that permits precise regulation or interruption of gas flow. The installation length is 250 mm, providing a practical working dimension for many common laboratory setups. Supplied as a single piece with a net weight of 0,026 kg, the tube offers a compact yet robust solution for gas-handling tasks. These inlet tubes from manufacturer Witeg are well suited to distillation, synthesis, inert-gas blanketing and other procedures that rely on secure conical-joint connections. The right-angled olive simplifies attachment of flexible tubing, while the valve cock gives the operator direct control over gas delivery during experiments. Compatible with flasks and assemblies fitted with matching NS 14/23 joints, the design supports reliable, leak-resistant performance in routine chemical and research environments. Technicians benefit from straightforward integration into existing glassware trains whenever controlled gas inlet is required.
This article is part of PVC, PTFE & other tubing, in Tubing, hoses & fittings.

Questions about Inlet tubes at 90°, with serrated hose
What is this article?
Inlet tubes at 90°, with serrated hose is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in PVC, PTFE & other tubing, inside Tubing, hoses & fittings, in Labware.
PVC is the flexible everyday tube for water and mild aqueous liquids. PTFE is the stiff, almost inert tube for solvents. Other polymers sit between them. The bore, the wall and the chemical resistance are the specification, and the tube is cut to length.
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.
