Description
Screw cap PP GL 45 natural is a closed polypropylene laboratory screw closure with GL 45 thread for reliable sealing of media bottles, reagent vessels and related GL 45 glassware. The solid closed design helps protect contents from contamination and evaporation during storage, transport and everyday laboratory use. Produced from durable PP in a natural finish, the cap is autoclavable at up to 140 °C and withstands standard sterilisation cycles while retaining a secure fit on the bottle neck. The neutral natural colour is well suited where unobtrusive appearance or content visibility through translucent closures is preferred. Supplied in packs of 10 pc(s), each cap has a net weight of 0,014 kg. These screw caps from manufacturer Witeg are compatible with common GL 45 bottle systems and serve as practical consumables for chemical, pharmaceutical and life-science laboratories. Typical uses include culture media, aqueous reagents, buffers and general sample storage whenever a thermally stable, closed PP GL 45 closure is required in research, teaching or routine analytical work.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap PP GL 45 nature
What is this article?
Screw cap PP GL 45 nature is the article on this page. Luminix Health distributes Witeg 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.
