Description
Nalgene™ three-way stopcock is a T-shaped laboratory stopcock that brings flexible on-site fluid transfer to liquid handling systems. It allows simple connection of two or even all three arms of the stopcock, supporting versatile routing of liquids in experimental and process setups. The plug opening is 4 mm and the plug is made of polypropylene, while the outlet ports are tubulated for secure tubing connections. This configuration suits routine laboratory fluid control where chemical resistance of polypropylene and a clear T-geometry are required. The stopcock type is specified as a shut-off stopcock for controlled flow paths. Supplied for laboratory plastics applications from manufacturer Thermo Scientific - Laboratory Plastics, it is offered as a single unit within a case of four. The design supports straightforward integration into existing transfer lines without complex adapters, making it a practical component for valves, stopcocks and shut-off duties in the lab.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

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 Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
