Description
Culture tubes with screw cap, DURAN®, are laboratory glass vessels fitted with a GL 18 thread and supplied in the dimensions Ø 16 × L 150 mm. These culture tubes support routine sample handling, incubation and short-term storage of liquid or solid media in microbiology, cell culture support work and general analytical workflows. The screw-cap closure helps reduce evaporation and contamination risk during transport between benches, incubators and storage areas, while the cylindrical format remains easy to rack, label and inspect visually. Manufactured by DWK Life Sciences, the DURAN® culture tube design is intended for everyday laboratory glassware use where a reliable threaded seal and standardised outer dimensions matter. Each pack contains 50 pc(s), giving laboratories a practical stock quantity for teaching labs, QC benches and research groups that process many parallel cultures. The tubes fit common GL 18 compatible caps and accessories already present in many glassware inventories. With a pack weight of 1,250 kg, the unit is straightforward to store and distribute within central stores. Choose these culture tubes when you need consistent DURAN® geometry, a secure screw closure and a ready multi-piece pack for continuous laboratory operations.

Questions about Culture tube with screw cap, DURAN®, thread GL 18, Ø 16 x L 150 mm, 50 unit(s)
What is this article?
Culture tube with screw cap, DURAN®, thread GL 18, Ø 16 x L 150 mm, 50 unit(s) 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.
