Description
Single way stopcocks, DURAN® with PTFE-cock are laboratory glass components intended for controlled single-path flow in jointed apparatus. Each stopcock is specified for joint 18,8, with a pipe diameter of 10 mm and a bore hole of 4 mm, supporting shut-off and routing duties in distillation, extraction and related glass assemblies. The DURAN® body is combined with a PTFE cock to provide smooth plug action within standard laboratory glassware trains. Packed as 2 pc(s) and offered from manufacturer DWK Life Sciences, these units fit modular setups where interchangeable single-way valves are required between connected sections. They belong to the established group of glass stopcocks and plugs used with laboratory glass vessels and consumables. Defined joint, pipe and bore dimensions help maintain consistent geometry when building or servicing glass lines for synthesis work-up, solvent handling or apparatus isolation. Lightweight construction keeps the components practical for fine glassware configurations in research, teaching and routine analytical environments that rely on DURAN® jointed systems and PTFE-plug stopcocks for everyday flow control.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Single way stopcocks, DURAN®, PTFE-cock, f. joint 18.8, pipe-Ø 10 mm
What is this article?
Single way stopcocks, DURAN®, PTFE-cock, f. joint 18.8, pipe-Ø 10 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.
