Description
Screw cap, LDPE, brown, GL 65 is a laboratory screw closure produced from low-density polyethylene (LDPE) in a brown colour and designed for GL 65 threaded bottles and vessels. The brown LDPE body provides protection from UV radiation and is therefore suitable for light-sensitive liquids that require reduced exposure during storage and handling. Supplied as a single piece, this brown screw cap supports secure closure of GL 65 laboratory bottles used for photosensitive reagents, standards and samples. Manufactured by lab-o-plastix, the cap combines the flexible sealing characteristics of low-density polyethylene with a pigmented finish intended to limit light transmission. LDPE remains a practical choice for laboratory screw closures thanks to its resilience and suitability for repeated opening and closing cycles on matching bottle necks. The GL 65 thread geometry aligns with standard laboratory containers of the corresponding size, enabling a reliable fit without extra adapters. Use this brown LDPE GL 65 screw cap wherever light-sensitive liquids must be protected from UV exposure while retaining a flexible polyethylene seal on GL 65 bottles, storage vessels or process containers in research and analytical environments.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap, LDPE, amber colour, GL 65
What is this article?
Screw cap, LDPE, amber colour, GL 65 is the article on this page. Luminix Health distributes lab-o-plastix 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.
