Description
DURAN® polyethylene stopper NS 10/19 is an ergonomic laboratory stopper intended for volumetric flasks, mixing cylinders and standing bottles. Manufactured from low-density polyethylene (LDPE), the stopper features a shape that makes opening and closing faster and more secure during everyday laboratory handling. Several grooves on the cone ensure optimal tightness and reliable sealing. Colour-coded inserts allow simple, rapid identification of the NS size; the colour system matches that used for Keck™ clamps, supporting clear visual organisation. A batch clock on the product indicates the production period by year and month, while the underside carries the polyethylene material designation “PE04”. Supplied without bottle, these stoppers from manufacturer Duran/DWK Life Sciences are well suited to the preparation and storage of standard solutions, colour-coded identification of vessels, and reduction of solvent evaporation. The combination of ergonomic form, grooved cone and standardised colour coding makes the NS 10/19 stopper a practical choice for routine analytical and preparative work in the laboratory.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about DURAN® Polyethylen-Stopper
What is this article?
DURAN® Polyethylen-Stopper is the article on this page. Luminix Health distributes DWK Life Sciences 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.
