Description
Single way stopcocks, DURAN® with PTFE-cock, provide dependable flow control for laboratory glass systems. This variant is designed for joint 12,5, an 8 mm pipe diameter and a 2,5 mm bore, supporting precise regulation of process streams in distillation, extraction and related glassware setups. DURAN® glass combined with a PTFE cock delivers chemical resistance and smooth plug action for routine laboratory media. The single-way configuration is intended for modular jointed apparatus where a compact shut-off element on 8 mm lines is needed. Supplied as 2 pc(s) from manufacturer DWK Life Sciences, the stopcocks fit research and analytical workflows that rely on interchangeable glass components. Their light weight aids assembly of multi-piece manifolds and custom apparatus. Matching joint 12,5 with the stated pipe and bore dimensions facilitates correct integration into standard ground-joint glassware. Applications include construction and maintenance of distillation trains, extraction circuits and controlled gas or liquid pathways in the laboratory environment.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Single way stopcocks, DURAN®, PTFE-cock, f. joint 12.5, pipe-Ø 8 mm
What is this article?
Single way stopcocks, DURAN®, PTFE-cock, f. joint 12.5, pipe-Ø 8 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.
