Description
Plastic stopper PP, NS 24/29 is a laboratory ground-joint stopper designed for reliable closure of standard NS glassware connections. Manufactured from polyethylene, it is shaped to give a secure seal on all common NS joints used in chemical, analytical and teaching setups. A hexagonal flat head keeps the stopper from rolling off the bench, while the hollow head form collects retained liquid and helps protect the working surface from drips or damage. Supplied in a pack of 10 pieces, this accessory from manufacturer ISOLAB Laborgeräte fits NS 24/29 conical joints found on flasks, condensers and multi-neck vessels. The plastic construction offers a lightweight, breakage-resistant alternative to glass stoppers and supports quick, repeatable sealing during routine handling. Consistent dimensions ensure interchangeability with standard European ground-joint glassware. These stoppers are practical everyday items for organic synthesis lines, distillation apparatus and general laboratory assemblies where a snug NS closure is required without additional adapters under normal conditions.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about stopper - P.E - 24/29
What is this article?
stopper - P.E - 24/29 is the article on this page. Luminix Health distributes ISOLAB 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.
