Description
Biogen sterile stoppers for neck 13,0–14,5 mm are cellulose laboratory stoppers intended for vessel necks with an internal diameter of 13,0 to 14,5 mm. Made from Zellstoff cellulose, they are air-permeable and bacteria-filtering, allowing controlled gas exchange while supporting a barrier against bacterial ingress during culture work, incubation, and intermediate storage of open vessels. The stoppers are sterilizable, so they can be prepared for repeated use in microbiology, teaching laboratories, and general wet-lab workflows that require a breathable rather than fully airtight closure.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.
Supplied in a pack of 1000 pieces from manufacturer Witeg, this bulk format suits high-throughput stations and shared media rooms. The Biogen cellulose stopper sits alongside cork, rubber, and silicone closures in the standard stopper range and is selected specifically by internal neck diameter. Net weight of the pack is 1,674 kg. Use these stoppers wherever a sterilizable, air-permeable cellulose plug is needed for necks in the 13,0–14,5 mm I-Ø range without introducing additional sealing materials or rigid caps.

Questions about Steristoppers for neck I-Ø 13 - 14,5 mm
What is this article?
Steristoppers for neck I-Ø 13 - 14,5 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.
