Description
DURAN® straight-through valve stopcock ''GU'' is a laboratory glass valve intended for dosing and flow regulation of liquids and gases under moderate leak-rate demands. The adjustable passage ranges from 0 to 6 mm, giving flexible control for a variety of experimental and process setups. Only DURAN® borosilicate glass 3.3 and PTFE come into contact with the medium, which supports clean, grease-free working thanks to the polished stopcock surface. An anti-unscrew lock stops the valve pin from being fully withdrawn, while the readjustable pin helps prolong the working life of the assembly. The handy design permits easy dismantling for cleaning or component exchange. As a glass article for further processing, it integrates readily into custom apparatus. Ideal for routine flow control tasks, this economical straight-through stopcock from manufacturer Duran/DWK Life Sciences combines chemical resistance with practical handling. Each unit is supplied as a single piece with a net weight of 0,034 kg and is suited to laboratory environments requiring dependable liquid and gas metering.

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.
