Description
Screw cap, LDPE, brown, GL 25 is a laboratory screw closure produced from low-density polyethylene in a brown finish for GL 25 threaded bottles. The brown LDPE body helps shield light-sensitive liquids from UV radiation, making the cap suitable for reagents, standards, and samples that require reduced light exposure during storage and handling. Supplied as a single piece, this closure from manufacturer lab-o-plastix fits matching GL 25 glass or plastic bottles commonly used in analytical, pharmaceutical, and research laboratories. Low-density polyethylene combines flexible sealing behaviour with practical chemical resistance for many aqueous and mild laboratory media, while the brown colouration supports protection of photosensitive contents. Ideal as a dedicated spare or replacement for light-sensitive workflows, it integrates into existing GL 25 bottle sets for dyes, indicators, photosensitive solutions, and other UV-sensitive preparations handled under standard laboratory conditions without altering established bottle inventories.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap, LDPE, amber colour, GL 25
What is this article?
Screw cap, LDPE, amber colour, GL 25 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.
