Description
Screw cap for culture tubes with sealing disc is a polypropylene (PP) closure fitted with a sealing disc and GL 14 thread, intended for disposable culture tubes used in microbiological and cell-culture work. In-vitro cultivation of animal and plant cells in nutrient media relies on suitable small-scale vessels; culture tubes are the preferred format for test runs and limited liquid volumes. This screw cap supports cultivation, storage and transport of small liquid quantities and enables handling of cell cultures under sterile conditions inside biosafety cabinets and clean-air hoods. Compatible with both DURAN® culture tubes and soda-lime glass tubes of the third hydrolytic class, the closure provides a reliable seal for routine laboratory workflows. Supplied in packs of 100 pieces from manufacturer Duran/DWK Life Sciences, the non-sterile polypropylene cap offers a practical solution for microorganism growth, short-term storage and safe transfer of samples. Net weight is 0,002 kg per unit, making the caps lightweight and easy to handle in high-throughput settings.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw Cap for Culture tubes, with seal
What is this article?
Screw Cap for Culture tubes, with seal is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
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.
