Description
Octagonal cap stopper NS 19 is a blue, round PE-HD ground joint stopper for oxygen bottles with a matching standard conical joint. Made from high-density polyethylene (HDPE), it pairs an octagonal cap head with a round stopper body sized for NS 19/26 laboratory glassware. The octagonal profile supports a firm grip when inserting or withdrawing the stopper from oxygen bottles and related apparatus, while the PE-HD construction offers a robust plastic closure for routine laboratory use. This plastic standard ground joint stopper is supplied as a single piece from manufacturer lab-o-plastix and sits within the category of Normschliff and plastic stoppers used on bottles and vessels fitted with the corresponding joint. The blue colour helps distinguish the fitting among other laboratory closures. Suitable wherever a PE-HD octagonal cap stopper with NS 19/26 geometry is required for oxygen bottles, the unit is offered as one piece for direct laboratory application without additional accessories.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about NS-plastic-stoppers, HDPE, blue, round, hexagonal for oxygen bottles, NS 19
What is this article?
NS-plastic-stoppers, HDPE, blue, round, hexagonal for oxygen bottles, NS 19 is the article on this page. Luminix Health distributes lab-o-plastix for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
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.
