Description
Pouring rings in polypropylene (PP) are practical laboratory accessories designed for controlled pouring from screw-neck bottles and similar vessels. These blue rings are specified for thread 45 and help guide liquid flow while reducing drips and spills during routine transfer, sampling, and media handling work. Manufactured from PP, they suit everyday labware setups where a lightweight, chemical-resistant polymer ring is preferred for bottle necks with a matching thread. Supplied as a pack of 10 pc(s) from manufacturer DWK Life Sciences, the set is convenient for equipping multiple bottles or keeping spares ready at the bench. With a total pack weight of 0,010 kg, the rings are easy to store and handle alongside other container seals and bottle accessories. They fit naturally into workflows involving laboratory glass and plastic vessels, reagent bottles, and general consumables used in research, quality control, and teaching laboratories. Use them wherever a dedicated pouring aid on thread 45 bottles improves cleanliness and handling consistency without adding bulk to the vessel.

Questions about Pouring rings, PP, blue, thread 45, 10 unit(s)
What is this article?
Pouring rings, PP, blue, thread 45, 10 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences 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.
