Description
Closure cap with 3/4'' internal thread in grey PVC provides a practical sealing solution for laboratory and industrial containers. This screw closure is intended for secure fitting on matching external threads, helping protect contents during storage, sampling and transport. Manufactured from durable PVC, the grey cap suits many routine laboratory applications involving aqueous media and common reagents where a straightforward mechanical seal is required. The 3/4'' internal thread supports compatibility with standard bottle and container necks used across laboratory and process workflows. Supplied as a single piece with a net weight of 0,016 kg, the compact design is convenient for everyday bench and storage use. This closure cap from manufacturer Bürkle fits typical screw-cap and originality-seal applications and supports clean, reliable handling of vessels. Laboratories needing simple PVC closures will find it integrates easily into existing container systems. The grey colour aids visual identification on the bench or in organised storage areas, while the robust construction withstands repeated handling in busy laboratory environments.

Questions about Captive cap 3/4'' internal thread, PVC, gray
What is this article?
Captive cap 3/4'' internal thread, PVC, gray is the article on this page. Luminix Health distributes Bürkle 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.
