Description
DURAN® angle valve stopcock ''GU'' is a laboratory glass valve designed for dosing and regulating liquids and gases under moderate leak-rate conditions. The adjustable bore from 0 to 4 mm offers versatile flow control in angled installations common to laboratory apparatus. Only DURAN® borosilicate glass 3.3 and PTFE contact the process medium, supporting grease-free handling via the polished stopcock surface. An anti-unscrew lock prevents the valve pin from being fully removed, while the readjustable pin contributes to longer service life. Compact construction makes dismantling simple for cleaning or part exchange. As a glass article intended for further processing, it fits readily into custom glass systems. This cost-effective angle stopcock from manufacturer Duran/DWK Life Sciences is ideal for everyday metering and flow adjustment of gases and liquids. Each unit comes as a single piece with a net weight of 0,033 kg and delivers dependable chemical resistance for routine laboratory applications.

Questions about DURAN® 90° Valve, ''GU''
What is this article?
DURAN® 90° 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.
