Description
Pouring ring PP green GL 45 is a polypropylene accessory designed for laboratory bottles fitted with a GL 45 thread. The green pouring ring forms a defined pour edge that helps guide liquids cleanly when dispensing reagents, buffers or culture media from standard laboratory bottles. Constructed from PP, the ring is autoclavable up to 140 °C, allowing repeated steam sterilisation as part of normal laboratory cleaning and reuse procedures. The green colour supports simple visual coding so that bottle groups can be recognised quickly during daily work. With a net weight of 0,001 kg, the ring remains lightweight yet practical for routine handling on the bench. Packs of 10 pc(s) make it easy to outfit several bottles at once or to maintain a small reserve of replacements. This pouring ring from manufacturer Witeg is intended for the common GL 45 neck standard used on many glass and plastic media bottles. It suits general laboratory applications where a durable polypropylene pouring ring and clear green colour identification are needed.

Questions about Pouring ring PP green GL 45
What is this article?
Pouring ring PP green GL 45 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Matériel de laboratoire.
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.
