Description
Cellulose stoppers, sterilisable, No. 19 are disposable laboratory stoppers intended for work with microbiological samples, cell cultures and similar applications. Formed from cellulose, they adapt snugly to the vessel opening while remaining air-permeable, allowing controlled gas exchange during incubation or storage. The stoppers are sterilisable up to 200 °C, making them suitable for thermal sterilisation protocols commonly used in microbiology and cell-culture laboratories. This pack contains 100 pieces from manufacturer Labbox under the STERISTOPPERS product type, providing a practical supply for routine single-use closure needs. Size No. 19 fits the corresponding range of container openings in this series. Pack net weight is 0,850 kg. These sterilisable cellulose stoppers support clean, breathable sealing of tubes and flasks in everyday laboratory practice where single-use, heat-tolerant stoppers are required for sample and culture work.

Questions about Sterilizable cellulose stopper, no. 19, 100 pcs
What is this article?
Sterilizable cellulose stopper, no. 19, 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.
