Description
Screw caps with lip seal gasket in polypropylene (PP), supplied in yellow and configured for thread 45, are closure components for laboratory bottles and related vessels. The integrated lip seal gasket supports a reliable seating interface when securing containers used for samples, media or process liquids in everyday lab workflows. Manufactured in PP and finished in yellow for quick visual identification, these caps suit organised storage and handling schemes where colour coding helps separate lines or contents. The pack contains 10 pc(s), giving a convenient stock quantity for glassware and plasticware stations. Approximate pack weight is 0,155 kg. These screw caps from manufacturer DWK Life Sciences fit the broader category of seals and accessories for laboratory containers, bottles and canisters. Thread 45 compatibility should be matched to corresponding bottle necks before use. They are intended as replaceable sealing closures rather than complete vessel systems. Select this yellow PP screw-cap format with lip seal gasket when a thread-45 closure is required for routine laboratory sealing and sample containment tasks.
This article belongs on Screw caps & closures, in Stoppers, caps & closures.

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