Description
Stopper NS stopcock 24/29 RD14 with olive is a complete laboratory glassware fitting that unites a standard ground joint NS 24/29, an NS stopcock, a bent tube carrying an RD 14 thread, a screw cap and an olive for hose attachment. The assembly enables secure, leak-tight connection of flexible tubing while the stopcock regulates flow of gas or liquid through the joint. Supplied ready for use as a single piece with a net weight of 0,043 kg, the stopper seats directly into any complementary NS 24/29 socket. The RD 14 threaded olive and matching screw cap provide a reliable mechanical clamp for the hose, reducing the risk of accidental disconnection under modest pressure or vacuum. Produced by Witeg, this component serves as a transition piece between rigid ground-joint apparatus and flexible tubing lines in synthesis, distillation and analytical setups. The bent geometry keeps the hose clear of the joint axis and simplifies routing inside fume cupboards. Laboratories requiring interchangeable standard-taper adapters with integrated flow control and hose coupling will find this stopper a practical modular element for glassware assemblies.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about SUCTION TUBE, WITH ST- STOPCOCK, BENT,
What is this article?
SUCTION TUBE, WITH ST- STOPCOCK, BENT, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
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.
