Description
Screw cap with seal GLS 80 is a polypropylene laboratory closure fitted with a lip seal for bottles and vessels that use the GLS 80 thread. Made from PP, the cap is heat-resistant up to +140 °C under steam and is autoclavable, so it can accompany glassware through repeated sterilisation cycles in routine laboratory practice. The lip seal supports a dependable fit for media, buffers, reagents and sample storage when matched with compatible GLS 80 containers. Supplied as a single piece with a net weight of 0,033 kg, this accessory from manufacturer Witeg suits chemical, life-science and pharmaceutical environments that need robust, heat-stable wide-neck closures. GLS 80 is a common laboratory thread format, making the cap a practical spare or replacement for existing bottle systems. Polypropylene construction combines mechanical durability with suitability for washing, handling and autoclave workflows. Laboratories can use the sealed GLS 80 screw cap in media preparation, temporary storage and transport without introducing non-autoclavable materials into the process chain.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap with lip seal GLS 80
What is this article?
Screw cap with lip seal GLS 80 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.
