Description
DURAN® straight stopcock, ground, without key is a precision glass shut-off component for laboratory apparatus, featuring an NS 29,2 joint and a 10 mm bore. Manufactured from borosilicate glass 3.3, it is supplied without a key and is intended for further processing into custom glass assemblies. Ground DURAN® straight stopcocks from manufacturer Duran/DWK Life Sciences are designed specifically as shut-off cocks and are fully compatible with DURAN® keys with groove, threaded keys and hollow DURAN® keys. They support coarse dosing of liquids; for fine metering, valve-style cocks are the preferred alternative. The precision-ground sealing surface ensures reliable performance once a matching key is fitted. With a net weight of 0,118 kg per piece, this glass article is well suited to installation in glass apparatus and devices where robust liquid control is required. Chemical resistance of borosilicate glass 3.3 combined with the standardised ground joint makes the stopcock a practical building block for laboratory glassware construction and everyday liquid-handling workflows.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about DURAN® Single Way Stopcock, ground, without key
What is this article?
DURAN® Single Way Stopcock, ground, without key 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.
