Description
Spiral stopper red is a solid laboratory stopper with a lower diameter of 12 mm, an upper diameter of 16 mm and a height of 44 mm. It features zero boreholes, making it suitable as a complete, hole-free closure for flasks, bottles and other laboratory vessels. The red colour supports quick visual identification during routine work. Each unit has a net weight of 0,00808 kg and is supplied in a practical pack of 10 pc(s). These spiral stoppers from manufacturer Deutsch & Neumann are intended for everyday sealing tasks in chemical, analytical and general laboratory environments where a reliable solid plug is required. Consistent dimensional tolerances support reproducible fits across multiple pieces. Originating from Germany, the stoppers belong to the standard stopper product group used for temporary or longer-term closure of glassware necks. The absence of bores ensures an uninterrupted seal without the need for tubing or inserts, simplifying handling in teaching, research and quality-control settings that demand straightforward, colour-coded laboratory stoppers.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Spiralstopper red, bottom diameter: 12 mm top diameter: 16 mm height: 44 mm
What is this article?
Spiralstopper red, 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.
