Description
Screw caps GL25 blue PP are closed polypropylene screw caps with a GL 25 thread and an integrated lip seal. Finished in blue, they provide a straightforward sealing solution for laboratory bottles and vessels that carry the matching GL 25 neck finish. The caps are supplied in a practical pack of 10 pc(s), each weighing 0,005 kg net, so they are easy to stock and handle on the bench. Manufactured from PP, the closed design combined with the lip seal supports secure closure during routine sample storage, handling and transport in research and analytical laboratories. These screw caps from manufacturer Witeg follow the standardised GL 25 thread geometry, ensuring compatibility with a wide range of glass and plastic laboratory bottles. The blue colour aids rapid visual identification among other closures and accessories. Lightweight and compact, they add negligible mass to glassware assemblies while remaining simple to fit and remove. Ideal for everyday laboratory workflows that require reliable GL 25 screw closures, they serve as a basic yet essential accessory for chemistry, biology and quality-control environments where consistent bottle sealing is needed.

Questions about Screw cap GL 25
What is this article?
Screw cap GL 25 is the article on this page. Luminix Health distributes Witeg 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.
