Description
Screw cap, LDPE, natural, GL 25 is a laboratory screw closure made from low-density polyethylene for sealing bottles and containers with a GL 25 thread. The natural LDPE material offers a flexible yet secure fit suited to everyday laboratory storage, sample transfer, and reagent handling where a dependable GL 25 interface is specified. Supplied as one piece, this cap from manufacturer lab-o-plastix pairs with matching GL 25 glass or plastic bottles used across analytical chemistry, life-science preparation, and general wet-lab work. Low-density polyethylene provides good chemical resistance for many aqueous and mild organic media while remaining easy to open and close by hand. The natural colour leaves the neck area unobtrusive and is appropriate when colour coding or light protection is not required. Use it as a standard spare or replacement closure to maintain consistent sealing performance across GL 25 bottle inventories for buffers, media, stock solutions, and routine laboratory liquids under normal working conditions.

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