Description
Pouring ring GL 45 with PP cap and ring (red) is a laboratory bottle accessory designed for GL 45 screw-thread bottles, combining a red polypropylene pouring ring with a matching PP cap for controlled pouring and secure closure. Rated for use up to 200 °C and identified as no. 20545, the red polypropylene pouring ring helps users obtain high tightness when sealing laboratory bottles such as DURAN GL 45 media bottles, while the integrated pouring geometry reduces drips during transfer. The red colour supports quick visual distinction from other bottle components. Supplied in a pack of 10 pieces from manufacturer Dinkelberg, this set is suited to routine media preparation, sample handling and reagent storage where GL 45 bottles are standard. The polypropylene construction matches common laboratory bottle systems and supports repeatable sealing performance in analytical, preparative and teaching environments. Each unit pairs the pouring ring with a PP cap so bottles can be closed tightly after dispensing without additional adapters.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Pouring Ring GL 45, with PP-Cap and Ring (red), 200° C Nr.20545, 10/PK
What is this article?
Pouring Ring GL 45, with PP-Cap and Ring (red), 200° C Nr.20545, 10/PK is the article on this page. Luminix Health distributes Dinkelberg 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.
