Description
Screw caps with lip seal gasket are blue polypropylene closures designed for thread 25 laboratory bottles and containers. The integrated lip seal supports a reliable seal on matching vessels used for sample storage, reagents and media handling. Each pack contains 10 pc(s) and has a net weight of 0,060 kg, convenient for stocking spare closures beside bottle inventories. These caps come from manufacturer DWK Life Sciences and suit routine sealing tasks in laboratory glass, vessels and consumables workflows. Polypropylene construction provides chemical resistance appropriate for many aqueous and solvent systems encountered in general lab use. The blue colour aids quick visual identification on the bench. Thread 25 compatibility ensures interchange with corresponding bottle necks in standard labware ranges. Typical applications include closing reagent bottles, sample containers and process vessels where a screw closure with gasket is preferred. Categories cover seals, hose connectors and accessories for containers, bottles, tins and canisters. Consistent PP screw-cap format helps maintain secure, reusable closures across research, quality-control and teaching laboratories.
This article belongs on Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw caps, w. lip seal gasket, PP, blue, thread 25, 10 unit(s)
What is this article?
Screw caps, w. lip seal gasket, PP, blue, thread 25, 10 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.
