Gas collection tubes, with 2 straight s

Gas sampling tube 1000 ml is a laboratory glass vessel designed for the collection, temporary storage and controlled transfer of gas samples. It features two NS one-way stopcocks that enable secure isolation of the sample volume and convenient connection to gas lines or analytical apparatus. The nominal capacity is 1000 ml, with a body diameter of 85 mm, a body length of 260 mm and a total length of 400 mm, providing a balanced geometry that remains practical on the laboratory bench. Manufactured by Witeg in Germany (Baden-Württemberg), the tube is supplied as one piece and has a net weight of 0,452 kg. The dual NS one-way stopcock configuration supports filling, sealing and subsequent release of gaseous samples without unnecessary exposure. This gas sampling tube is well suited to analytical chemistry, process monitoring and quality-control environments that require a robust glass sampling vessel with ground-joint stopcock closures for reliable containment of gas samples prior to measurement or further processing.
