Description
Screw cap GL 50 with bore is a polypropylene laboratory closure for vessels fitted with a GL 50 thread. The grey PP cap features a bore diameter of Ø 38 mm, giving ample clearance for tubing, probes or process accessories while remaining seated on the bottle neck. Supplied as 1 pc, the component has a net weight of 0,0253 kg and is intended for setups that require open access through a large-thread closure. GL 50 necks appear on selected reagent bottles and process containers; this cap lets users adapt those vessels for sampling, aeration or sensor work without changing the container itself. Manufactured by Witeg, the grey polypropylene construction offers a practical, chemically resistant option for chemical, pharmaceutical and life-science laboratories. Its defined bore and standard GL 50 thread support consistent, repeatable bottle configurations in routine and pilot-scale workflows where a secure yet accessible closure is essential.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw caps GL 50 top with hole
What is this article?
Screw caps GL 50 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.
