Description
Sterile stoppers 13 mm made of cellulose are laboratory consumables intended for closing culture tubes, flasks and other glass vessels in microbiological and general laboratory work. The cellulose plugs form a soft, compressible seal that supports practical vessel closure while remaining easy to insert and remove by hand. A pack contains 1000 pieces, giving laboratories a convenient bulk supply for routine media work, incubation setups and teaching practicals. The 13 mm diameter matches common small-neck glassware used in research, quality control and educational settings. These stoppers from manufacturer Dinkelberg belong to a straightforward range of lab materials focused on everyday sterile technique and sample handling. Cellulose construction is well suited where a breathable, fibre-based plug is preferred over rigid caps. Country of origin is Germany. Use them for short- to medium-term closure of tubes and small bottles during culture maintenance, transport within the lab or temporary storage of prepared media. The uniform size supports consistent packing across batches and simplifies stock replenishment for high-throughput benches.

Questions about Steri-stopper 13mm, pulp, 1000 pcs
What is this article?
Steri-stopper 13mm, pulp, 1000 pcs is the article on this page. Luminix Health distributes Dinkelberg 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.
