Description
DURAN® PURE Premium screw caps with GL 25 thread provide secure closure for laboratory bottles and containers used in research, sampling, and routine media handling. The caps are supplied in STERCILIN® packaging as a convenient pack of 20 pieces, supporting organised storage and ready access at the bench. With a pack weight of 0,380 kg, the set is practical for laboratory stockrooms and day-to-day workflows. The GL 25 thread size aligns with standard narrow-neck laboratory glassware configurations commonly used for reagents, buffers, and sample vessels. These premium screw caps belong to the DURAN® PURE range from manufacturer DWK Life Sciences and are intended for laboratories that require consistent bottle closures across general labware and sampling applications. They fit naturally into bottle and container systems used in virus research support work, campaign laboratory setups, and everyday containment tasks where dependable sealing of GL 25 necks is required. The STERCILIN® packaging format helps keep the 20-unit pack tidy until use, while the DURAN® PURE Premium designation identifies this closure option within established DURAN® laboratory bottle ecosystems.

Questions about DURAN® PURE Premium screw caps, STERCILIN®-packaging, GL 25, 20 unit(s)
What is this article?
DURAN® PURE Premium screw caps, STERCILIN®-packaging, GL 25, 20 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.
