Description
Screw cap, with bore, PP, GL 18, yellow is a polypropylene laboratory screw closure for GL 18 threaded bottles used in chemical handling, sample storage, and process setups. The yellow PP construction delivers a robust, lightweight seal that resists many common laboratory chemicals, while the integrated bore permits passage of tubing, sensors, or other inserts without removing the cap. The closure is steam-sterilisable at 121 °C, making it suitable for autoclave workflows in media preparation and microbiology. GL 18 threading ensures compatibility with standard laboratory bottles of the same neck finish, so the cap can be swapped onto existing vessels as needed. From manufacturer lab-o-plastix, this bored yellow screw cap supports colour-coded organisation of reagents and process lines on the bench. It is intended as a functional accessory rather than a solid seal, ideal where continuous access, venting, or instrument feed-through is required. Offered as a single piece for convenient pairing with matching GL 18 bottles and related polypropylene laboratory closures in everyday laboratory practice.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap, with aperture, PP, GL 18, yellow
What is this article?
Screw cap, with aperture, PP, GL 18, yellow 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.
