Description
Screw cap GL 25 with bore is a laboratory closure equipped with a 15 mm central opening and intended for vessels that use a GL 25 thread. The red cap allows tubing, probes, sensors or similar accessories to pass through the lid while the threaded connection stays firmly seated on the bottle or flask neck. It supports chemical, biological and analytical applications that need open access through the closure, such as continuous sampling, inline measurement or controlled atmosphere work. Each piece has a net weight of 0,009 kg and is supplied in packs of 10 pc(s). These screw caps from manufacturer Witeg are compatible with standard GL 25 laboratory glassware and plasticware found in research, quality-control and teaching laboratories. The red finish provides clear visual identification on the bench. Offering a larger bore matched to the GL 25 thread size, this screw cap delivers a practical solution for adapting closed vessels to flexible experimental setups without changing the underlying thread geometry.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw caps GL 25 top with hole
What is this article?
Screw caps GL 25 top with hole 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.
