Description
Screw cap with lip seal, red, GL 45, PP is a polypropylene laboratory closure for secure sealing of bottles and vessels fitted with a GL 45 thread. The red polypropylene body features an integrated lip seal that supports a reliable seal against the vessel neck during storage, handling and routine laboratory operations. The GL 45 thread matches widely used laboratory glassware and plastic bottles for reagents, media and samples, making the cap straightforward to integrate into existing bottle systems.
This article is part of Screw caps & closures, in Stoppers, caps & closures.
Polypropylene (PP) construction delivers the mechanical strength and chemical resistance typical of this laboratory material. The product is specified as resistant to steam up to 140 °C, allowing use in procedures that involve steam within the thermal limits of polypropylene. The red colour provides a clear visual cue for colour-coding vessel contents, hazard groups or process stages in busy laboratory environments.
This screw cap with lip seal comes as a single piece from manufacturer lab-o-plastix and is suited to laboratories that standardise on GL 45 necks and require a durable, colour-coded PP closure. It serves everyday sealing tasks in sample preparation, media work and general wet-chemistry settings where a dependable red GL 45 lip-seal cap is needed.

Questions about Screw cap with lip seal, red, GL 45, PP
What is this article?
Screw cap with lip seal, red, 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.
