Description
Biogen sterile stoppers for neck 13,0–16,0 mm are cellulose laboratory stoppers designed for vessel necks with an internal diameter from 13,0 to 16,0 mm. Fabricated from Zellstoff cellulose, they are air-permeable and bacteria-filtering, supporting controlled aeration while contributing a bacterial barrier for culture vessels, media bottles, and related laboratory containers. The stoppers are sterilizable, making them appropriate for preparation cycles in microbiology, cell-culture support areas, and general laboratory practice where a breathable cellulose closure is preferred to rigid caps or fully sealed plugs.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.
A pack of 1000 pieces is offered from manufacturer Witeg, giving ample stock for busy benches and shared facilities. Positioned in the cellulose stopper category next to cork, rubber, and silicone alternatives, the Biogen format is specified by internal neck diameter for consistent fit across the 13,0–16,0 mm I-Ø window. Net weight per pack is 2,088 kg. Select these stoppers when sterilizable, air-permeable, bacteria-filtering cellulose plugs are needed for the stated neck range in high-volume laboratory use.

Questions about Steristoppers for neck I-Ø 13 - 16 mm
What is this article?
Steristoppers for neck I-Ø 13 - 16 mm is the article on this page. Luminix Health distributes Witeg 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.
