Description
Pouring rings GL 32 are laboratory accessories for Simax laboratory bottles with a GL 32 thread. Made from red polybutylene terephthalate (PBT), they are specified for a maximum temperature of 180 °C and support controlled pouring of liquids from glass reagent bottles. The GL 32 thread match ensures a secure fit on compatible bottle necks, helping reduce drips and improve handling during routine transfers of reagents and solutions. Packed in units of 10 pieces from manufacturer Marienfeld, the rings suit chemistry, analytical, and general laboratory workflows that rely on standardised bottle accessories. PBT construction provides dimensional stability together with thermal resistance within the stated temperature limit, so the rings remain practical for many heated or elevated-temperature bench situations. Their red colour aids quick visual identification among other bottle components. As dedicated pouring rings for Simax bottles, they integrate into existing glassware sets without changing bottle geometry and support safer, cleaner liquid handling in everyday laboratory use.

Questions about Pouring rings GL 32,
What is this article?
Pouring rings GL 32, is the article on this page. Luminix Health distributes Marienfeld 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.
