Description
Screw cap GL 14 with bore is a laboratory closure fitted with a central opening of Ø 9,5 mm and intended for vessels that carry a GL 14 thread. The red cap allows tubing, probes, sensors or other accessories to pass through the closure while the threaded connection remains secure on the bottle or flask neck. Designed for everyday use in chemical, biological and analytical laboratories, it supports setups that require open access through the lid, such as continuous sampling, gas exchange or inline monitoring. Each piece has a net weight of 0,004 kg and is supplied in practical packs of 10 pc(s). These screw caps from manufacturer Witeg integrate readily with standard GL 14 laboratory glassware and plasticware. The distinctive red colour aids quick visual identification on the bench and in storage. Suitable for research, quality-control and teaching environments, the GL 14 screw cap with bore provides a straightforward way to adapt closed vessels for flexible experimental configurations without altering the underlying thread geometry.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap GL 14 top with hole
What is this article?
Screw cap GL 14 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.
