Description
Single way stopcocks, DURAN® with PTFE-cock, are laboratory glass valves for controlled single-path flow. Configured for joint 14,5, a 9 mm pipe diameter and a 2,5 mm bore, they support reliable regulation of liquids and gases in distillation, extraction and general apparatus work. The DURAN® body and PTFE cock plug offer chemical resistance together with smooth, consistent operation under typical laboratory conditions. These components suit modular ground-joint systems that require a single-way stopcock on 9 mm tubing connections. Available in a pack of 2 pc(s) from manufacturer DWK Life Sciences, they serve research, teaching and analytical laboratories building or servicing glass assemblies. Lightweight design helps keep complex setups manageable. Dimensional alignment to joint 14,5 and the specified pipe and bore sizes supports proper fit within standard jointed glassware. Common uses include distillation trains, extraction lines and vacuum or inert-gas manifolds where interchangeable glass stopcocks are preferred.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Single way stopcocks, DURAN®, PTFE-cock, f. joint 14.5, pipe-Ø 9 mm
What is this article?
Single way stopcocks, DURAN®, PTFE-cock, f. joint 14.5, pipe-Ø 9 mm is the article on this page. Luminix Health distributes DWK Life Sciences 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.
