Description
neoChoice Steri stoppers for single use are disposable cellulose plugs designed for the sterile closure of test tubes, Erlenmeyer flasks and culture flasks with a 45 mm neck. Formed from cellulose, they provide an air-permeable yet bacteria-filtering barrier that supports sterile working conditions while allowing gas exchange during incubation or storage. The tapered geometry measures 61 mm at the top diameter, 45 mm at the bottom diameter and 62 mm in height, giving a secure fit on matching vessel necks. These single-use stoppers are autoclavable up to 200 °C, so they can be sterilised with the glassware before inoculation or sampling. Supplied in packs of 25 pieces from manufacturer neolab - Labor, they suit routine microbiology, cell culture and general laboratory workflows where reliable, disposable sterile closures are preferred over reusable stoppers. The cellulose construction remains dimensionally stable under autoclave conditions and is intended for one-time use to reduce cross-contamination risk between batches or cultures.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about neoChoice Steri-Stopfen für den Einmalgebrauch, für Hals 45 mm
What is this article?
neoChoice Steri-Stopfen für den Einmalgebrauch, für Hals 45 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.
