Description
Poly stopper for NS 24/29 is a low-density polyethylene (LDPE) ground-joint stopper intended for reliable closure of laboratory vessels fitted with standard taper joints of size NS 24/29. Manufactured from polyethylene of low density, the stopper offers a lightweight, chemically resistant seal that seats cleanly in matching glassware without the need for grease in many routine applications. Supplied as a single piece, it is suited to flasks, adapters and other NS 24/29 apparatus used in synthesis, sample preparation and general laboratory work. The compact form factor and low net weight of 0,007 kg make handling and storage straightforward on the bench or in drawer systems. Physical packaging dimensions are modest (depth 0,025 m, width 0,01 m, height 0,005 m), supporting efficient inventory of consumable stoppers. This poly stopper from manufacturer Hirschmann provides a practical plastic alternative to glass stoppers where impact resistance and ease of use are preferred. It is intended for closing vessels under typical laboratory conditions and integrates directly with standard European ground-joint glassware of the stated NS size.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about POLY STOPPER NS 24/29
What is this article?
POLY STOPPER NS 24/29 is the article on this page. Luminix Health distributes Hirschmann 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.
