Description
Screw caps with lip seal gasket are polypropylene laboratory closures finished in grey and matched to thread 45 bottle necks. They serve as practical sealing components for laboratory containers, bottles and related vessels used in routine sample handling, preparation and storage. Made from PP, the caps offer the chemical resistance and durability expected of polypropylene labware, while the integrated lip seal gasket supports dependable closure on compatible thread 45 systems. Colour-coded grey, they help laboratories keep bottle fleets organised and visually consistent across benches and storage areas. Each pack contains 10 pc(s) and has a pack weight of 0,150 kg, making the unit convenient for restocking common consumable inventories. These screw caps sit within the seals, hose connectors and accessories category for containers, bottles, tins and canisters, and pair naturally with standard laboratory glass and plastic vessels that use thread 45. Available from manufacturer DWK Life Sciences, they provide a straightforward option for laboratories standardising on grey PP screw caps with lip seal gaskets for everyday workflows.
This article belongs on Screw caps & closures, in Stoppers, caps & closures.

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