Description
Straight-through valve stopcock DURAN® GU with a passage of 0–2,5 mm is intended for flow regulation of liquids or gases where moderate leak-rate requirements apply. GU valve stopcocks feature an anti-unscrew lock that prevents complete removal of the valve pin. The adjustable valve pin extends the service life of the stopcock. Media flowing through the valve contact only DURAN® glass and PTFE, allowing grease-free operation thanks to the polished stopcock surface. The handy valve design permits easy dismantling and handling. Offered as a cost-effective alternative, this straight-through valve stopcock from manufacturer Duran/DWK Life Sciences is ideal for dosing and regulating gases and liquids in laboratory work. It is supplied as a glass article for further processing into apparatus. Manufactured from borosilicate glass 3.3, the component provides reliable yet economical control in setups that do not demand the lowest possible leak rates.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about DURAN® Straight Valve, ''GU''
What is this article?
DURAN® Straight Valve, ''GU'' 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.
