Description
Plastic stopper PP, NS 10/19 is a ground-joint stopper intended for reliable sealing of NS connections in everyday laboratory glassware. Manufactured for a precise fit on NS 10/19 joints, it provides a practical alternative to glass stoppers where impact resistance and light weight are preferred. A hexagonal flat head keeps the stopper from rolling off the work surface, reducing loss and contamination risk at the bench. The hollow head design collects retained liquid and helps protect the working surface from drips or staining. Supplied in a pack of 10 pieces from manufacturer ISOLAB Laborgeräte, these stoppers support efficient stocking of common joint sizes across teaching, quality-control and research laboratories. The plastic construction is suited to routine closure of flasks, bottles and apparatus carrying aqueous or mild organic media. Compact and easy to handle, the NS 10/19 format fits smaller volumetric and reaction vessels used in sample preparation and general wet-chemistry workflows.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about stopper - P.E - 10/19
What is this article?
stopper - P.E - 10/19 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.
