Description
neoChoice Steri stoppers for single use, for neck 28 mm, are disposable cellulose stoppers intended for the sterile closure of test tubes, Erlenmeyer flasks and culture flasks. They present an upper diameter of 28 mm, a lower diameter of 23 mm and a height of 30 mm, matching 28 mm necks commonly found on laboratory glassware. Made from cellulose (Zellstoff), the stoppers are air-permeable and bacteria-filtering, supporting gas exchange while helping limit microbial ingress during incubation or short-term storage. They are autoclavable up to 200 °C, so they can be included in standard sterilisation routines before use. Pack size is 500 pieces, suited to high-throughput microbiology, media preparation and culture work. These single-use Steri stoppers from manufacturer neolab - Labor provide a practical tapered plug for sterile sealing without permanent fittings. Their cellulose construction and defined dimensions make them a straightforward choice wherever breathable, sterile closures are required on tubes and flasks with 28 mm necks in research and routine laboratory settings.
This article belongs on Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about neoChoice Steri-Stopfen für den Einmalgebrauch, für Hals 28 mm
What is this article?
neoChoice Steri-Stopfen für den Einmalgebrauch, für Hals 28 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 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.
