Description
NS stopper made of polyethylene (PE-HD) NS 7/16 is a laboratory stopper produced from high-density polyethylene (HDPE) for standard ground joints of size NS 7/16. This PE-HD stopper provides a practical sealing solution for laboratory glassware that uses the corresponding NS joint standard. The high-density polyethylene material combines mechanical stability with chemical resistance typical of HDPE components used in laboratory environments. Supplied as 1 pc, the stopper is suitable for routine assembly and closure of glass apparatus in research, teaching and analytical laboratories. Manufactured by Hecht, the item belongs to the laboratory materials category and is identified under UNSPSC classification for laboratory stoppers and closures. Its polyethylene construction keeps the component lightweight while maintaining dimensional accuracy for the NS 7/16 joint. The stopper can be inserted and removed repeatedly without damaging the ground surface when handled correctly. High-density polyethylene offers good resistance to many aqueous solutions and common laboratory reagents, supporting reliable day-to-day use. This NS 7/16 PE-HD stopper therefore forms a straightforward, durable accessory for sealing standard ground joints in everyday laboratory work.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Stoppers of HDPE, interchangeable NS 7/16
What is this article?
Stoppers of HDPE, interchangeable NS 7/16 is the article on this page. Luminix Health distributes Hecht 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.
