Description
Single way stopcocks, DURAN® with PTFE-cock are precision glass components for single-path flow control in laboratory apparatus. This variant is configured for joint 18,8, with a pipe diameter of 13 mm and a bore hole of 6 mm, making it suitable for shut-off and routing in distillation, extraction and general jointed glass systems. A DURAN® glass body paired with a PTFE cock supports dependable plug operation across routine wet-chemistry workflows. Supplied as a pack of 2 pc(s) from manufacturer DWK Life Sciences, the stopcocks integrate into modular glass setups that require interchangeable one-way valves. They form part of the glass stopcocks and plugs range used alongside laboratory glass vessels and consumables. Clear specification of joint, pipe and bore dimensions aids reproducible assembly when connecting sections of glass lines for solvent transfer, fraction collection or apparatus isolation. The compact, lightweight design remains practical for research, quality-control and teaching laboratories that standardise on DURAN® jointed glassware with PTFE-plug stopcocks for everyday liquid or gas handling tasks.
This article belongs on Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Single way stopcocks, DURAN®, PTFE-cock, f. joint 18.8, pipe-Ø 13 mm
What is this article?
Single way stopcocks, DURAN®, PTFE-cock, f. joint 18.8, pipe-Ø 13 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 Matériel de laboratoire.
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.
