Description
Screw caps GL 25 are laboratory bottle closures intended for vessels with a GL 25 screw thread. They are produced from black plastic and incorporate a PE-LD sealing insert that supports a tight, resealable fit for everyday storage and handling of reagents, buffers, and process liquids. The larger GL 25 format matches medium-capacity threaded bottles widely used in analytical chemistry, life-science, and industrial quality laboratories. Consistent thread geometry and the soft PE-LD liner help limit leakage and solvent loss when bottles are moved between benches, cabinets, or instruments. These screw caps from manufacturer Marienfeld come in packs of 10 pieces, suitable for maintenance stocks or equipping small sets of matching bottles. The black plastic body offers a professional appearance and can assist with light protection when used on suitable containers. Select GL 25 screw caps when you need dependable plastic closures with PE-LD gaskets for standard GL 25 laboratory bottle systems in research or production environments.

Questions about Screw caps GL 25,
What is this article?
Screw caps GL 25, is the article on this page. Luminix Health distributes Marienfeld 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.
