Description
Stopcock for threaded connections is a compact laboratory valve intended for desiccators and related vacuum apparatus. It features a PTFE spindle with a self-sealing valve stopcock, giving controlled shut-off on compatible threaded ports. Type Mobilex construction includes over-rotation protection that helps safeguard the spindle during frequent opening and closing. With a net weight of 0,022 kg, the unit stays light yet robust for everyday laboratory handling. Supplied as one piece from manufacturer Witeg, this stopcock supports evacuation, venting and isolation tasks on glassware fitted with threaded connections. The PTFE spindle offers smooth travel and chemical resistance suited to common laboratory atmospheres. Self-sealing design contributes to dependable closure under typical desiccator vacuum levels, while over-rotation protection reduces the risk of mechanical damage at full travel. Suitable for drying cabinets, vacuum desiccators and modular glass systems that use interchangeable stopcocks, it fits standard laboratory glassware inventories. Reliable sealing performance and straightforward threaded mounting make it a practical spare or replacement component for routine vacuum work.

Questions about Stopcock for thread-connection
What is this article?
Stopcock for thread-connection 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.
