Description
Three-way T-stopcock with 2,5 mm bore and NS 14,5 joint is a glass laboratory valve for directing and switching fluid or gas paths in vacuum and general apparatus setups. It features solid, interchangeable NS glass plugs fitted with thread and screw connection plus an O-ring, supporting secure seating and convenient plug exchange during maintenance or configuration changes. The T-geometry enables three-way routing typical of manifold, distillation, and vacuum-line work where controlled diversion between ports is required. Bore diameter of 2,5 mm balances flow capacity with fine control for analytical and preparative glassware. Manufactured by Starke, the stopcock is supplied as a single piece for integration into standard NS 14,5 assemblies. Suitable for research, teaching, and quality-control laboratories that rely on interchangeable glass stopcocks with threaded retention and O-ring sealing. Clear joint size and bore specification simplify matching to existing ground-joint systems and tubing connections without guesswork on compatibility.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Three-way T-cocks 2.5 mm bore, NS 14.5 with solid, interchangeable
What is this article?
Three-way T-cocks 2.5 mm bore, NS 14.5 with solid, interchangeable is the article on this page. Luminix Health distributes Starke 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.
