Description
DURAN® straight stopcock, ground, without key is a borosilicate glass 3.3 component engineered for shut-off applications in laboratory glass systems. This ground joint stopcock body carries an NS 24 taper and an 8 mm bore and is supplied without the key so that it can be finished and paired according to the user’s requirements. Ground DURAN® straight stopcocks are compatible with DURAN® stopcock keys featuring a groove, with threaded keys and with hollow DURAN® keys. They are intended primarily for coarse dosing of liquids and for incorporation into glass apparatus and instruments. For fine metering, valve-type stopcocks are the more suitable choice. Produced by manufacturer Duran/DWK Life Sciences under the DURAN® trademark, the article is a glass component for further processing, offering standardised geometry for reliable assembly. The single-piece unit has a net weight of 0,067 kg and is supplied as one piece, ready for integration into custom laboratory setups where controlled liquid flow is required.
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.
