Description
DURAN® plastic stopper NS 60/46 is a white octagonal laboratory stopper manufactured from low-density polyethylene (LDPE) for secure closure of glassware with standard ground joints. It features an octagonal top and blue insert, conforming to DIN 12254 for consistent fit and reliable sealing performance. Designed for the storage of reagents and chemicals, the polyethylene construction provides chemical resistance and durability in routine laboratory environments. The octagonal shape offers a firm, ergonomic grip that simplifies opening and closing of flasks and bottles while maintaining a tight seal. Supplied as a single piece, this stopper from manufacturer Duran/DWK Life Sciences supports safe reagent handling and long-term storage in analytical and research settings. Its lightweight design allows easy insertion and removal without compromising joint integrity. The white body with contrasting blue insert aids quick visual identification on the bench. Ideal for standard joint applications where a non-contaminating, reusable plastic closure is required to protect sample quality during storage.

Questions about DURAN® Plastic Stopper, Polyethylene, white, octagonal
What is this article?
DURAN® Plastic Stopper, Polyethylene, white, octagonal 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.
