Description
Stopper with valve stopcock and lateral olive NS 29/32 is a precision laboratory glassware fitting intended for standard ground-joint systems that require both secure closure and regulated flow. It features an NS 29/32 taper joint combined with an integrated valve stopcock and a lateral olive for convenient tubing attachment. Net weight is 0,031 kg, yielding a compact and lightweight component suitable for distillation trains, reaction vessels, vacuum lines and general adapter applications. The design aligns with transition pieces, standard-joint reducers and screw-coupling accessories widely used in chemical and analytical laboratories. Produced by Witeg, the stopper ensures reliable joint compatibility and straightforward handling in daily experimental practice. Supplied as 1 pc(s), it integrates readily into existing glassware collections based on NS 29/32 connections. The lateral olive simplifies hose connection while the valve stopcock provides precise on-demand control, supporting efficient and reproducible laboratory workflows without the need for additional intermediate fittings.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Suction tube lateral olive ST 29/32
What is this article?
Suction tube lateral olive ST 29/32 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.
