Description
Single way stopcock, DURAN®, PTFE-cock is a laboratory glass stopcock component designed for controlled flow in distillation, extraction and general glassware assemblies. It is specified for joint 29,2 with a pipe diameter of 18 mm and a borehole of 10 mm, supporting reliable shut-off and transfer in chemical and analytical setups. Manufactured from DURAN® borosilicate glass with a PTFE cock, the unit combines chemical resistance with smooth, low-friction operation of the plug. This configuration suits connections where a single-way valve is required on standard jointed apparatus. Supplied as 1 pc and weighing 0,242 kg, the stopcock integrates readily into modular glass systems used for synthesis work-up, solvent handling and vacuum or pressure-assisted transfers. The PTFE cock helps reduce sticking and simplifies cleaning between runs. From manufacturer DWK Life Sciences, the piece belongs to the glass stopcocks and plugs category within laboratory glass components for distillation and extraction. It is intended for routine laboratory use where dimensional fit to joint 29,2 and an 18 mm pipe with 10 mm bore are specified by the apparatus design.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Single way stopcock, DURAN®, PTFE-cock, f. joint 29.2, pipe-Ø 18mm, boreh. 10 mm
What is this article?
Single way stopcock, DURAN®, PTFE-cock, f. joint 29.2, pipe-Ø 18mm, boreh. 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.
