Description
Stopcock attachment with 2 NS stopcocks is a modular glassware component fitted with two NS stopcocks and a rubber stopper for controlled transfer of liquids or gases in laboratory assemblies. The dual stopcocks allow independent regulation of flow paths when the attachment is connected to compatible flasks or apparatus, while the rubber stopper provides a secure seal at the mounting point. Supplied as 1 pc, the unit has a net weight of 0,08 kg and a gross weight of 0,08 kg, making it a lightweight addition to multi-piece glass setups. Belonging to miscellaneous glass construction elements, it is suited to distillation, filtration, reaction or sampling lines that require stopcock-controlled routing. From manufacturer Witeg and produced in Germany (Baden-Württemberg), the attachment integrates readily into existing NS-jointed systems without adding significant bulk. Laboratories assembling flexible glass manifolds or needing an extra pair of stopcocks with a stopper seal will find this Hahnaufsatz a practical building block for precise fluid handling on the bench.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Stopcock connector with 2 taps, with r
What is this article?
Stopcock connector with 2 taps, with r is the article on this page. Luminix Health distributes Witeg 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.
