Description
Cellulose stoppers, sterilisable, No. 37 are disposable stoppers for microbiological samples, cell cultures and comparable laboratory work. The cellulose construction is air-permeable and conforms well to the vessel mouth, providing a breathable closure for culture flasks and sample containers. They withstand sterilisation up to 200 °C, enabling preparation for aseptic procedures within that temperature range. Supplied as a pack of 25 pieces with a net weight of 0,960 kg, the No. 37 size matches containers specified for this stopper number. These STERISTOPPERS from manufacturer Labbox offer a practical single-use option where gas exchange and a snug fit matter more than a fully sealed cap. Suitable for microbiology and cell-culture benches, they combine straightforward handling with thermal resistance to 200 °C and the stated air-permeable cellulose design, without extending beyond the manufacturer’s described properties and pack data.

Questions about Sterilizable cellulose stopper, no. 37, 25 pcs
What is this article?
Sterilizable cellulose stopper, no. 37, 25 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.
