Description
Closure cap with internal thread, PP, 1'' is a polypropylene screw closure for laboratory containers and fittings that use a matching external thread. Made from polypropylene (PP), the cap combines chemical resistance with mechanical durability for many aqueous and organic laboratory applications. The internal thread design engages securely on compatible 1'' connections, helping maintain a reliable seal during storage, sampling, transport, or fluid-transfer steps. Supplied as a single piece with a net weight of 0,015 kg, this component from manufacturer Bürkle fits bottle systems, sampling devices, and process accessories where a lightweight plastic closure is preferred. Polypropylene construction keeps the part easy to handle while supporting repeated opening and closing under normal laboratory conditions. The product is supplied non-sterile and is appropriate for general laboratory and technical environments that require dependable threaded seals. It supports screw-cap and original-seal workflows in chemical, environmental, and industrial laboratory settings where secure containment of liquids and samples is required.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Closing cap, inner thread, PP, 1''
What is this article?
Closing cap, inner thread, PP, 1'' is the article on this page. Luminix Health distributes Bürkle 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.
