Description
Cellulose stoppers, sterilisable, No. 9, are single-use laboratory closures intended for microbiological samples, cell cultures, and related culture-vessel work. The cellulose material conforms closely to the container opening, helping secure the vessel while remaining air-permeable so gas exchange can continue during incubation or storage. These stoppers are sterilisable up to 200 °C, allowing integration into standard thermal sterilisation workflows before use. Supplied as a pack of 100 pieces from manufacturer Labbox, size No. 9 supports consistent fitting across compatible flasks and tubes in routine laboratory practice. Designed for disposable application, they reduce cleaning effort and help limit carry-over between batches in microbiology and cell-culture settings. The combination of snug fit, thermal sterilisation tolerance, and air permeability makes these cellulose stoppers a practical choice for laboratories that need reliable, breathable closures for culture work without permanent sealing. Suitable for everyday media preparation, sample incubation, and short-term culture handling where single-use stoppers are preferred.

Questions about Sterilizable cellulose stopper, no. 9, 100 pcs
What is this article?
Sterilizable cellulose stopper, no. 9, 100 pcs is the article on this page. Luminix Health distributes Labbox 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.
