Description
Pouring rings in polypropylene are laboratory accessories finished in grey and intended for thread 45 bottle systems. They support cleaner, more controlled pouring from laboratory containers and bottles during sample transfer, media handling and routine dispensing tasks. Made from PP, the rings combine low weight with the chemical resistance expected of polypropylene consumables used with laboratory glass and plastic vessels. Grey colouring aids visual organisation and matches grey-coded thread 45 closures or bottle fleets already in use. Packs contain 10 pc(s) and have a pack weight of 0,006 kg, making them simple to keep on hand for everyday laboratory restocking. These components belong to the seals, hose connectors and accessories category for containers, bottles, tins and canisters. Supplied by manufacturer DWK Life Sciences, the grey PP pouring rings are a practical choice for laboratories that rely on thread 45 systems and require consistent pouring accessories for orderly bottle handling without added complexity.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Pouring rings, PP, grey, thread 45, 10 unit(s)
What is this article?
Pouring rings, PP, grey, 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.
