Description
Nalgene™ three-way stopcock is a T-shaped laboratory stopcock that brings flexible on-site liquid transfer control to tubing-based setups. The three-way design allows simple connection of two arms or all three arms of the stopcock, supporting diversion, isolation, or combined flow paths in fluid-handling systems. It is specified as a stopcock with a 2 mm plug opening, a polypropylene plug, and tubulated outlet ports for hose connection. This configuration suits temporary or permanent transfer lines where compact, lightweight plastic fittings are preferred over glass stopcocks. The unit is offered as 1 pc, with packaging referenced as one per pack and four per carton (case of 4). Gross weight is 0,090 kg. Produced under the Nalgene™ line from manufacturer Thermo Scientific - Laboratory Plastics, the stopcock supports laboratory plastics workflows in research, process development, and general lab fluid routing. Use it wherever a durable polypropylene three-way valve element is needed to join tubing runs and manage multi-path liquid transfer without complex manifold hardware.

Questions about Nalgene™ Three-way Stopcock
What is this article?
Nalgene™ Three-way Stopcock is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics 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.
