Description
Desiccator stopcock for lid tubulature is a precision glass fitting intended for laboratory desiccators fitted with a tubulated lid. It combines a ground core joint NS 24/29 with a solid plug NS 14,5 and a bore of 2,5 mm, allowing controlled evacuation and venting of the desiccator chamber. Manufactured from DURAN tubing, the stopcock offers the chemical resistance and mechanical stability expected of borosilicate laboratory glassware. Supplied as a single piece with a net weight of 0,039 kg, it is designed for straightforward installation in matching lid openings. The solid plug geometry supports a reliable seal when closed, while the 2,5 mm bore provides adequate flow for routine vacuum and gas-exchange operations. This component from manufacturer Witeg is suited to drying procedures, storage under reduced pressure or inert atmosphere, and general desiccator work in analytical, quality-control and research laboratories. Its standardised NS joints ensure compatibility with common desiccator lid configurations that use an NS 24/29 tubulature connection.

Questions about Stopcock for dessicator lids
What is this article?
Stopcock for dessicator lids 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.
