Description
Screw caps GL 45 with bore are laboratory closures made for bottles and vessels carrying a GL 45 thread. Each red cap includes a bore of 34 mm, providing a generous opening for tubing, probes, sensors or other accessories while the cap stays fixed on the neck. The pack contains 10 pc(s), and every piece has a net weight of 0,025 kg, making the set convenient for stocking multiple workstations. GL 45 is a widely used thread on larger reagent and media bottles, so these caps suit sampling, gas exchange and instrument-insertion applications in chemical, biotech and pharmaceutical laboratories. From manufacturer Witeg, the design combines a clear colour coding with a defined bore geometry that supports repeatable setup of open-access bottle systems. Laboratories can keep standard GL 45 vessels in service while adapting them for continuous monitoring or transfer lines, helping streamline everyday handling without specialised adapters.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw caps GL45 bore
What is this article?
Screw caps GL45 bore 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.
