Description
Screw caps with lip seal gasket are polypropylene laboratory closures finished in blue and designed for thread 45 bottle necks. The integrated lip seal supports a reliable seal on compatible vessels used for sample storage, media handling and general laboratory workflows. Manufactured from PP, these caps combine chemical resistance suitable for routine lab use with a practical, easy-to-grip form that fits standard threaded containers in this size class. Supplied as a pack of 10 pc(s) and weighing 0,170 kg per unit pack, they are convenient consumables for stocking bottle and container systems in research, quality-control and teaching laboratories. The blue colour aids quick visual identification among mixed glassware and plasticware on the bench. These screw caps from manufacturer DWK Life Sciences sit within seals and accessories for laboratory containers, bottles and canisters, where consistent thread geometry and a defined gasket interface matter for everyday sealing performance. Use them wherever thread 45 PP closures with a lip seal gasket are specified for temporary or longer-term closure of laboratory vessels without adding unnecessary complexity to the setup.
This article belongs on Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw caps, w. lip seal gasket, PP, blue, thread 45, 10 unit(s)
What is this article?
Screw caps, w. lip seal gasket, PP, blue, thread 45, 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 Matériel de laboratoire.
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.
