Description
Screw cap with lip seal, blue, GL 45, PP is a laboratory screw closure for glass bottles and vessels with a GL 45 neck finish. Produced from polypropylene (PP), the blue cap combines a robust threaded body with an integrated lip seal to promote secure sealing in standard laboratory practice. Polypropylene delivers mechanical strength and broad chemical resistance for many aqueous media and organic reagents encountered in research and quality-control environments. Manufacturer information indicates resistance to steam up to 140 °C, making the closure suitable for autoclave-compatible glassware where the cap must tolerate elevated temperature and moisture. Supplied as one piece, this GL 45 screw cap from manufacturer lab-o-plastix functions as a practical spare or replacement for larger media bottles, reagent containers and similar laboratory vessels. The blue colour assists visual organisation of contents, process lines or storage areas. Typical uses include sample storage, media preparation, buffer handling and general bottle-closure work requiring a durable polypropylene screw cap with lip-seal geometry on the GL 45 thread.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

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