Description
Stopcock for tubulure cover NS 24/29 is a laboratory stopcock designed for desiccator tubulure covers, featuring a self-sealing valve stopcock and a PTFE spindle with over-rotation protection. The NS 24/29 joint size matches common desiccator lid and tubulure interfaces, supporting secure fit and controlled venting or isolation during drying and storage work. The self-sealing valve arrangement and PTFE spindle help maintain reliable operation while the over-rotation safeguard protects the spindle mechanism in daily use. Offered as one piece with a net weight of 0,026 kg, this component is practical for routine glassware setups that require a dedicated stopcock on the tubulure cover. From manufacturer Witeg, it sits in the desiccator stopcock range and is intended for laboratory environments where grease-free, controlled sealing at NS 24/29 is needed. Its compact form and defined joint geometry support straightforward installation on compatible covers. Choose this stopcock when a self-sealing PTFE-spindle valve for tubulure covers is specified in research, analytical, or general laboratory desiccator systems.

Questions about Stopcock for lids ST 24/29
What is this article?
Stopcock for lids ST 24/29 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.
