Description
Cap with olive NS 29/32 is a laboratory glassware closure featuring a straight olive and a ground-joint sleeve in the NS 29/32 standard size. It provides a secure seal on matching conical joints while the olive supplies a side connection for flexible tubing used to introduce or remove gases and liquids. The straight olive configuration supports simple hose attachment in distillation, reaction and vacuum assemblies. Supplied as 1 pc with a net weight of 0,031 kg and a gross weight of 0,031 kg, the component originates from Germany (Baden-Württemberg) and integrates into common European ground-joint glassware sets. Laboratory professionals choose this style of jointed cap when closing larger flasks, adapters or receivers that still require a tubing outlet. From manufacturer Witeg, the cap is suited to organic synthesis, analytical chemistry and teaching environments where durable, reusable glass connections are essential. The NS 29/32 designation ensures interchangeability with widely used conical joints, permitting quick assembly and dependable sealing during everyday laboratory work.

Questions about Suction tube, straight, ST 29/32
What is this article?
Suction tube, straight, ST 29/32 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.
