Description
Screw cap GL 60 with bore is a laboratory closure designed for GL 60 bottle necks and vessels that require open access through the lid. The central bore measures 48 mm in diameter, allowing tubing, probes, sensors or other inserts to pass through while the cap remains secured on the thread. Manufactured from grey glass-fibre-reinforced PBT, the cap combines mechanical strength with chemical resistance typical of polybutylene terephthalate composites used in laboratory environments. It is autoclavable and remains dimensionally stable at temperatures up to 160 °C, supporting repeated sterilisation cycles and elevated-temperature work. Supplied as a single piece from manufacturer Witeg, this screw cap suits media bottles, reaction vessels and process setups where a large central opening is needed without sacrificing a reliable GL 60 seal. The robust polymer construction and defined bore geometry make it a practical choice for sampling, continuous addition or instrument integration on GL 60 glassware.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap GL 60 with hole
What is this article?
Screw cap GL 60 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.
