Description
Screw cap, PP, natural, GL 25 is a polypropylene laboratory closure designed for bottles and vessels with a GL 25 thread. Manufactured from polypropylene (PP) in a natural colour, this screw cap provides a practical sealing option for routine sample handling, storage and preparation work in chemical, analytical and life-science laboratories. The GL 25 thread geometry supports secure mating with matching glass or plastic laboratory bottles commonly used for reagents, buffers and process intermediates. Supplied as a single piece, the cap is autoclavable up to a maximum of 121 °C, allowing integration into standard steam-sterilisation workflows when heat resistance of the polymer is required. For safe autoclaving practice, the closure should be unscrewed before the cycle and placed on the bottle rather than left tightly fastened. This natural PP screw cap from manufacturer lab-o-plastix suits everyday laboratory organisation where a clear, unpigmented finish and reliable GL 25 compatibility are preferred. It fits well within collections of screw closures and original-seal accessories used across teaching, research and quality-control environments that rely on standardised GL thread systems.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap, PP, natural, GL 25
What is this article?
Screw cap, PP, natural, GL 25 is the article on this page. Luminix Health distributes lab-o-plastix 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.
