Description
Sterile stoppers 14 mm made of cellulose are laboratory consumables for closing culture tubes, flasks and related glassware in microbiological and general laboratory practice. The cellulose material yields soft, compressible plugs that seat readily in matching necks and can be handled without special tools. Each pack supplies 1000 pieces, supporting efficient stock management for routine culture work, media preparation and teaching laboratories. The 14 mm diameter fits widely used vessel neck sizes in research, diagnostics and educational environments. These stoppers from manufacturer Dinkelberg form part of a practical lab-materials range aimed at everyday sterile technique and sample protection. Fibre-based cellulose construction is appropriate where a breathable plug is preferred to solid screw caps or rubber bungs. Country of origin is Germany. Typical uses include temporary closure during incubation, short-term storage of prepared media and transport of tubes within the laboratory. Consistent sizing helps maintain uniform packing across batches and simplifies reordering for busy benches that consume stoppers in high volume.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Steristopfen 14 mm, Cellulose, 1000 St./Pk
What is this article?
Steristopfen 14 mm, Cellulose, 1000 St./Pk is the article on this page. Luminix Health distributes Dinkelberg for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Matériel de laboratoire.
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.
