Description
Stopcock for side tubulure NOVUS NS 24/29 is a laboratory valve designed for desiccator side arms with a standard ground joint. The Novus-type fitting carries an NS 24/29 joint and combines a PTFE spindle with a self-sealing valve stopcock for controlled vacuum and venting operations. Integrated over-rotation protection helps prevent spindle damage during repeated actuation. Net weight is 0,023 kg, keeping the component compact on the apparatus. Supplied as a single piece from manufacturer Witeg, this stopcock is intended for side tubulures on NOVUS-style desiccators and comparable laboratory glassware. The PTFE spindle ensures smooth operation and chemical resistance appropriate for drying and storage applications. Self-sealing valve action supports leak-tight closure under normal desiccator vacuum conditions. The NS 24/29 ground joint provides a standardized interface matching common European laboratory glassware. Ideal as a replacement or spare for vacuum desiccators, the stopcock enables reliable isolation of the chamber atmosphere. Durable construction and protective features make it suitable for frequent open–close cycles in analytical and preparative laboratories.

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