Description
Standard ground glass joint stoppers in PE are laboratory stoppers intended for vessels fitted with standard taper ground glass joints in size NS 45/40. Each piece carries a brown insert that supports quick visual identification when several joint sizes are handled side by side. The product is offered as a single unit with a stated weight of 0,030 kg, making it straightforward to stock individual sizes as needed. These stoppers sit within the labware category of stoppers and clamps for laboratory glass, vessels and consumables, specifically stoppers with standard taper. Polyethylene construction provides a practical closure option for routine sealing of compatible ground joints in research, teaching and analytical environments. The NS 45/40 taper matches common laboratory glassware dimensions, so the stopper seats directly on corresponding necks and openings without intermediate adapters. Colour coding via the brown insert helps keep multi-joint assemblies organised and reduces the risk of size mix-ups during setup or changeover. From manufacturer DWK Life Sciences, this PE standard ground glass joint stopper supports everyday glassware workflows where a simple, size-specific PE closure is required. Pack size is one piece per unit for flexible replenishment of larger joint sizes.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Standard ground glass joint stoppers, PE, NS 45/40, insert brown, 1 unit(s)
What is this article?
Standard ground glass joint stoppers, PE, NS 45/40, insert brown, 1 unit(s) 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.
