Description
Screw cap, closed, PP, GL 25, without seal, red is a polypropylene laboratory closure for GL 25 threaded bottles and containers. The closed design without an integrated seal suits applications that need a straightforward screw finish rather than a gasketed or lined cap. Red colour coding helps staff distinguish vessel contents, process stages or dedicated media lines at a glance. Offered as one piece per unit, the cap is steam sterilisation resistant at 121 °C and can therefore accompany glassware or plasticware through standard autoclave programmes. The GL 25 thread matches common laboratory bottle necks of this size, supporting secure hand-tightening in everyday sample preparation, storage and transport. Suitable for research, quality-control and teaching environments, this closed PP screw cap from manufacturer lab-o-plastix combines durable polypropylene construction with clear visual identification. It is a practical choice whenever a seal-free, autoclave-compatible GL 25 closure in red is required for organised laboratory workflows.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap, closed, PP, GL 25, without seal, red
What is this article?
Screw cap, closed, PP, GL 25, without seal, red 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.
