Description
neoChoice Steri stoppers for single use are disposable cellulose stoppers intended for the sterile closure of test tubes, Erlenmeyer flasks and culture flasks with a 15 mm neck. Air-permeable and bacteria-filtering, they support sterile handling while permitting gas exchange through the plug. The tapered body measures 17 mm at the top diameter, 12 mm at the bottom diameter and 37 mm in height, giving a secure seat in standard laboratory necks of this size. They are autoclavable up to 200 °C, so they can be included in routine sterilisation cycles used in microbiology, cell culture and general wet-lab work. Offered in a pack of 1000 pieces from manufacturer neolab - Labor, these single-use Zellstoff stoppers provide a convenient alternative to reusable closures when contamination control and rapid changeover matter. Typical applications include sealing culture vessels, reagent tubes and small flasks in research, teaching and quality-control laboratories. The cellulose construction combines breathability with a bacteria-filtering barrier without the need for additional adapters on common European glassware formats.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about neoChoice Steri-Stopfen für den Einmalgebrauch, für Hals 15 mm
What is this article?
neoChoice Steri-Stopfen für den Einmalgebrauch, für Hals 15 mm is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Matériel de laboratoire.
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.
