Description
Screw caps made of PP with GL 63 thread are laboratory closures intended for secure sealing of bottles, vessels and related containers in routine analytical and preparative work. Fabricated from polypropylene, they match the widely used GL 63 neck finish found on many reagent and sample bottles, supporting consistent closure when caps are replaced or stocked as consumables. Each pack contains 12 pc(s) and has a total weight of 0,252 kg, giving laboratories a practical quantity for everyday vessel management without excess bulk. These screw caps from manufacturer Vitlab fit naturally into workflows involving containers, bottles, tins and canisters, as well as seals and hose-connector accessories. Polypropylene construction is suitable for general laboratory handling of aqueous media and many common reagents under standard bench conditions. The GL 63 format helps maintain a reliable mechanical seal during short-term storage, transport between workstations and temporary holding of samples or stock solutions. As replaceable labware components they simplify maintenance of bottle fleets in research, quality-control and teaching environments. Use them wherever dependable PP screw closures for GL 63 openings are required in day-to-day laboratory organisation.

Questions about Screw caps made of PP, GL 63, 12 unit(s)
What is this article?
Screw caps made of PP, GL 63, 12 unit(s) is the article on this page. Luminix Health distributes Vitlab for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Matériel de laboratoire.
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.
