Description
DURAN® Original screw cap GL 45 with lip seal is a polypropylene (PP) laboratory bottle closure finished in blue and provided with an integrated lip seal. The seal delivers reliable closure performance and allows drip-free pouring when used with a matching pouring ring, thereby supporting clean and safe laboratory practice. This Original series cap is available within a colour assortment that also covers green, yellow and grey versions supplied with colour-coordinated pouring rings. Colour differentiation greatly simplifies the separation of different media and virtually rules out accidental interchange of screw caps as well as carry-over of substances. Distinctive marking on the cap further reduces the risk of mix-ups. Offered as a single piece from manufacturer Duran/DWK Life Sciences, the PP component (net weight 0,015 kg) is intended for autoclaving of media and reagents, short-term storage of samples and media, and clear colour-based identification. Compatible with GL 45 threads, the robust polypropylene construction withstands routine laboratory use while the lip-seal design promotes consistent drip-free dispensing and secure sealing throughout everyday scientific workflows.

Questions about DURAN® Original Laboratory Bottle Screw Cap, linerless, with lip seal, PP
What is this article?
DURAN® Original Laboratory Bottle Screw Cap, linerless, with lip seal, PP 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.
