Description
Spiral stopper yellow is a solid laboratory stopper offering a lower diameter of 12 mm, an upper diameter of 16 mm and a height of 44 mm. With zero boreholes it provides a complete, uninterrupted seal for flasks, bottles and similar laboratory vessels. The yellow colour enables rapid visual sorting and identification in organised workspaces. Each stopper has a net weight of 0,00808 kg and comes in a convenient pack of 10 pc(s). These spiral stoppers from manufacturer Deutsch & Neumann serve everyday sealing requirements in chemical, analytical and general laboratory practice where a solid plug without openings is preferred. Uniform dimensions help ensure consistent seating across multiple items. Produced in Germany, the stoppers form part of the standard stopper range used for temporary or extended closure of glassware. The lack of bores eliminates the need for additional tubing or inserts, supporting straightforward handling in teaching laboratories, research facilities and quality-control environments that benefit from clearly colour-coded laboratory stoppers.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Spiralstopper yellow, bottom diameter: 12 mm top diameter: 16 mm height: 44 mm
What is this article?
Spiralstopper yellow, bottom diameter: 12 mm top diameter: 16 mm height: 44 mm is the article on this page. Luminix Health distributes Deutsch & Neumann for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
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.
