Description
Screw cap, PP, natural, GL 14 is a polypropylene laboratory screw closure for bottles with a GL 14 thread. Made from polypropylene (PP) in a natural colour, it is intended for secure sealing of laboratory vessels used in sample handling, storage and routine analytical work. The closure is autoclavable up to a maximum of 121 °C; before autoclaving, the cap should be unscrewed and placed on the bottle rather than left tightly closed. This handling note helps maintain reliable performance during steam sterilisation cycles common in microbiology and general laboratory practice. Offered as a single piece, the GL 14 thread matches standard laboratory bottle necks, supporting consistent fit across compatible glass or plastic containers. From manufacturer lab-o-plastix, this natural PP screw cap suits laboratories that need a heat-tolerant polymer closure for GL 14 systems. It is appropriate for workflows that combine everyday sealing with occasional autoclave treatment, helping keep bottle necks protected while reagents or samples are processed under controlled laboratory conditions.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap, PP, natural, GL 14
What is this article?
Screw cap, PP, natural, GL 14 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.
