Description
Closed screw cap GL 60 is a high-performance laboratory bottle closure designed for vessels with a GL 60 thread. Produced from glass-fibre-reinforced polybutylene terephthalate (PBT) and fitted with a PTFE-coated gasket, this solid cap combines elevated thermal stability with reliable sealing performance. The material system is autoclavable and resistant up to 160 °C, making the closure suitable for sterilisation cycles and applications that involve elevated process temperatures. The non-perforated design prevents vapour exchange and protects contents from contamination during storage, transport and thermal treatment. Net weight is 0,055 kg, giving a balanced feel for frequent handling on the bench. Supplied as a single piece from manufacturer Witeg, the cap integrates with standard GL 60 laboratory and media bottles used throughout chemical, biotechnological and pharmaceutical laboratories. The PTFE-coated seal enhances chemical resistance at the sealing face, supporting use with aqueous media and many common solvents. This robust closed screw cap is well suited to demanding laboratory workflows that require both thermal endurance and dependable leak resistance without additional ports or openings.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap GL 60 top closed
What is this article?
Screw cap GL 60 top closed 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.
