Description
Dropping attachment, PE-HD, GL 25 is a laboratory dropping closure for bottles with a matching GL 25 neck finish. Made from PE-HD (high-density polyethylene), it provides a screw-on interface intended for controlled, dropwise delivery of liquids in routine laboratory work. The GL 25 thread follows a widely used laboratory bottle standard, so the attachment can be fitted directly onto compatible PE or glass bottles that share this neck size. Supplied as a pack of 12 pieces, the format suits benches that equip several reagent bottles at once or keep spare closures ready for change-over. The item belongs to the dropping-attachment / dropping-closure product family and is aimed at everyday dispensing, sample preparation support and general wet-lab organisation where PE-HD is an acceptable contact material. Country of origin is Germany. Available from manufacturer Vitlab, the attachment keeps installation simple: screw onto the GL 25 neck, check the seat, and use for drop formation as required by the workflow. No additional adapters are described for standard GL 25 systems, helping laboratories standardise bottle tops across multiple stations while maintaining a consistent PE-HD material choice for the dropper head.
This article is part of Closures (other), in Stoppers, caps & closures.

Questions about Screw-cap with dropping insert, PE-HD, GL 25
What is this article?
Screw-cap with dropping insert, PE-HD, GL 25 is the article on this page. Luminix Health distributes Vitlab for laboratory use. It sits in Closures (other), inside Stoppers, caps & closures, in Labware.
These are the closures that are not a plain screw cap, a rubber stopper or a ground-glass stopper. The question is still the same: does the closure match the mouth, and does the material survive the contents.
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.
