Description
Screw cap with lip seal, green, GL 45, PP is a polypropylene laboratory closure intended for secure sealing of bottles and vessels with a GL 45 thread. The green polypropylene body is combined with an integrated lip seal that supports a reliable interface between the cap and the vessel neck during storage, handling and routine laboratory use. GL 45 is a widely adopted laboratory thread standard, so this closure fits common reagent bottles, media bottles and sample containers used across research and analytical workflows.
This article is part of Screw caps & closures, in Stoppers, caps & closures.
Made from polypropylene (PP), the cap offers the mechanical robustness and chemical resistance associated with this laboratory plastic. According to the manufacturer data it is resistant to steam up to 140 °C, which supports use in processes that involve steam exposure within the thermal limits of polypropylene. The green colour assists visual identification and simple colour-coding of vessel contents or process stages on the bench or in storage.
This screw cap with lip seal is supplied as a single piece from manufacturer lab-o-plastix and suits laboratories that standardise on GL 45 bottle systems and need a practical, colour-differentiated PP closure for everyday sealing tasks in sample preparation, media work and general wet-chemistry environments.

Questions about Screw cap with lip seal, green, GL 45, PP
What is this article?
Screw cap with lip seal, green, GL 45, PP is the article on this page. Luminix Health distributes lab-o-plastix 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.
