Description
Pouring rings GL 45 are laboratory bottle accessories made from blue polypropylene for use with Simax laboratory bottles. The GL 45 thread matches standard GL 45 bottle necks, helping guide liquid flow during pouring and transfer steps at the bench. Polypropylene (PP) construction allows thermal exposure up to a maximum of 140 °C, which is suitable for many routine washing and handling conditions associated with reusable glass media and reagent bottles. Supplied from manufacturer Marienfeld, the rings are packed in units of ten pieces for convenient stock replenishment in preparation rooms and general laboratories. As dedicated pouring rings they complement GL 45 screw-thread bottles where cleaner dispensing and reduced rim wetting are desired during day-to-day media, buffer or solvent handling. The blue colour aids quick visual identification among other bottle fittings. These components form a simple mechanical interface between bottle and user without altering the bottle thread itself, and they integrate into existing Simax GL 45 workflows already established in many laboratories.

Questions about Pouring rings GL 45,
What is this article?
Pouring rings GL 45, is the article on this page. Luminix Health distributes Marienfeld 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.
