Description
Silicone hollow stopper with outer diameter 27 mm provides a flexible sealing solution for laboratory flasks, bottles and vessels requiring a larger neck fit. Manufactured from silicone, it offers the elasticity and chemical resistance needed for sample storage, reaction work and general laboratory closures where an inert seal is preferred. The 27 mm outer diameter ensures a firm match to corresponding openings, supporting secure containment and reduced risk of contamination or solvent loss. Individual net weight is 0,00557 kg. Available in packs of 10 pieces from manufacturer Deutsch & Neumann, these hollow silicone stoppers suit chemistry, life-science, pharmaceutical and industrial laboratory settings. The hollow design simplifies handling during insertion and removal while maintaining structural integrity under normal lab conditions. Silicone construction allows repeated use and straightforward cleaning, making the stoppers a practical choice for everyday glassware sealing. They belong to the established category of silicone stoppers used across research and quality-control workflows.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about hollow-stopper Silikon, outer Ø 27 mm
What is this article?
hollow-stopper Silikon, outer Ø 27 mm is the article on this page. Luminix Health distributes Deutsch & Neumann 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.
