Description
Standard ground glass joint stoppers made of polyethylene (PE) are laboratory closures sized for NS 14/23 ground taper joints. Each stopper carries a yellow insert so the joint size can be recognised at a glance when several taper formats are in use on the same bench. The PE body gives a light, durable seal on flasks, adapters and other glassware that rely on standard ground connections, supporting short-term closure against dust and evaporation during preparation, transfer or teaching work. Packs contain 10 pieces and weigh 0,030 kg, making them easy to stock at multiple stations. Colour coding of the insert reduces mix-ups between NS sizes in busy chemistry and life-science laboratories. These stoppers from manufacturer DWK Life Sciences fit everyday workflows that need reliable temporary sealing of ground joints without glass-on-glass stoppers. They sit in the stoppers-with-standard-taper category of labware consumables and are intended for routine vessel handling rather than specialised high-vacuum or long-term storage applications.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Standard ground glass joint stoppers, PE, NS 14/23, insert yellow, 10 unit(s)
What is this article?
Standard ground glass joint stoppers, PE, NS 14/23, insert yellow, 10 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.
