Description
Disposable conical stopcock, nominal size 2, is a single-use laboratory valve component for controlling liquid or gas flow in glassware and apparatus setups that employ conical (tapered) stopcock geometry. Nominal size 2 defines the standardised bore and taper class used for matching stopcock barrels and plugs in common laboratory configurations, supporting straightforward integration into existing conical-stopcock systems. Designed as a disposable (Einweg) item, it is intended for applications where single-use handling reduces cleaning effort, cross-contamination risk, or downtime between experiments. Supplied as one piece, the stopcock suits routine fluid handling, sampling lines, titration and chromatography accessories, and general lab assemblies that require a compact conical valve of this nominal size. Produced by Schlee, it belongs to the laboratory-material range for research, teaching, and quality-control environments. Clear nominal-size identification (size 2) simplifies ordering and replacement. Choose this disposable conical stopcock when a standardised, single-use flow-control element is preferred over reusable ground-glass stopcocks for the intended workflow.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Single way stopcocks, size 2
What is this article?
Single way stopcocks, size 2 is the article on this page. Luminix Health distributes Schlee 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.
