Description
Screw cap with bore, PBT, GL 45, red is a laboratory screw closure designed for reliable sealing on GL 45 threaded vessels and bottles. Manufactured from polybutylene terephthalate (PBT), the red cap combines mechanical strength with chemical resistance suited to everyday lab handling of reagents, media and sample containers. A central bore allows tubing, probes or other accessories to pass through while the threaded body maintains a secure fit on matching GL 45 necks. Short-term thermal load capacity reaches 200 °C, supporting brief exposure during warming steps or autoclave-adjacent workflows where temperature spikes may occur. The vivid red colour aids quick visual identification on crowded benches and storage shelves. Supplied as a single piece from manufacturer lab-o-plastix, this PBT screw cap with bore integrates easily into bottle and flask systems used in analytical chemistry, quality control and general laboratory organisation. It is intended for use wherever a durable GL 45 closure with an access opening is required without altering the underlying vessel geometry.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap with aperture, made of PBT, GL 45, red
What is this article?
Screw cap with aperture, made of PBT, GL 45, 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.
