Description
Screw cap with bore, PP, GL 25, red is a laboratory screw closure made from polypropylene for GL 25 threaded bottles and vessels. The central bore lets tubing, probes or similar accessories pass through the cap while the thread maintains a secure fit on standard GL glassware. Finished in red for quick visual coding in multi-setup workflows, the polypropylene body offers the chemical resistance and mechanical robustness expected of PP in routine laboratory handling. Supplied as 1 piece, it is intended for everyday use in chemistry, biology and analytical laboratories where GL 25 necks are common. The design is steam-sterilisable at 121 °C, so it can accompany autoclave cycles when clean or sterile working conditions are required. This cap from manufacturer lab-o-plastix integrates into familiar laboratory bottle systems that need both a reliable closure and an access opening. Polypropylene construction supports typical cleaning regimes and solvent exposure within the material’s known compatibility range. Suitable for media bottles, reagent containers and process setups that combine sealing with feed-through capability, the red GL 25 screw cap with bore provides a practical, colour-coded option for organised bench and instrument work.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap, with aperture, PP, GL 25, red
What is this article?
Screw cap, with aperture, PP, GL 25, red 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.
