Description
Cap with NS stopcock and straight olive NS24/29 is a laboratory glassware accessory intended for secure sealing and regulated fluid or gas transfer on equipment equipped with standard ground joints. Featuring an NS 24/29 joint together with an integrated stopcock and straight olive outlet, it permits dependable tubing connections and accurate flow control in experimental configurations. Offered in a pack size of 1 pc with a net weight of 0,06 kg, the component provides a practical solution for analytical chemistry, synthesis work, distillation trains and routine laboratory operations needing reliable closures. Manufactured by Witeg, the cap integrates smoothly with standard flasks and vessels, supporting assembly in vacuum systems, gas introduction lines or liquid-handling setups. Its sturdy form is well suited to research, quality-control and educational laboratories that rely on standardised joints and consistent stopcock performance. The straight olive facilitates simple hose attachment, increasing flexibility for filtration, reaction observation or inert-gas applications while preserving an effective seal at the ground joint interface.

Questions about SUCTION TUBE, WITH ST-STOPCOCKS, STRAI
What is this article?
SUCTION TUBE, WITH ST-STOPCOCKS, STRAI is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
