Description
Standard ground glass joint stoppers in polyethylene (PE) are sized for NS 24/29 ground taper joints commonly found on medium laboratory flasks and adapters. Each unit includes a green insert for rapid visual identification of the joint size among mixed taper sets. The PE body delivers a light yet secure temporary seal, supporting vessel protection during preparation, transfer and teaching laboratory work. Packs of 10 pieces weigh 0,140 kg and are convenient for stocking multiple benches or shared stores. Colour coding of the insert helps reduce selection errors when several NS formats are in simultaneous use. These stoppers from manufacturer DWK Life Sciences suit general chemistry and life-science workflows that need reliable short-term closure of ground joints without glass stoppers. They form part of the stoppers-with-standard-taper labware range and are intended for routine handling rather than high-vacuum or extended storage applications.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Standard ground glass joint stoppers, PE, NS 24/29, insert green, 10 unit(s)
What is this article?
Standard ground glass joint stoppers, PE, NS 24/29, insert green, 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.
