Description
Poly stopper PE NS 24/29 is a laboratory plastic stopper manufactured from high-density polyethylene (HDPE) for standard ground joints of size NS 24/29. It provides a secure, lightweight seal for flasks, bottles and other glassware fitted with matching NS taper joints, helping to limit evaporation and protect contents from contamination. The HDPE construction offers durability and chemical resistance suitable for routine laboratory handling of aqueous media and many common solvents while remaining shatterproof. Each item is supplied as 1 pc and seats directly into the corresponding ground joint without adapters. These stoppers are practical for storage, reaction work-up and general glassware closure in chemical, analytical and teaching laboratories. Available from manufacturer IDL GmbH, the product belongs to the established groups of standard ground joint stoppers and plastic stoppers. The NS 24/29 designation follows the widely used European joint standard, ensuring interchangeability with existing glassware sets. High-density polyethylene keeps the stopper robust yet easy to insert and remove during daily laboratory workflows.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about PE stopper, for standard ground joint ST 24/29
What is this article?
PE stopper, for standard ground joint ST 24/29 is the article on this page. Luminix Health distributes IDL GmbH 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.
