Description
Screw cap PP GL 45 red is a closed polypropylene laboratory screw closure with GL 45 thread intended for tight sealing of media bottles, reagent containers and other GL 45 laboratory glassware. The closed construction supports controlled storage and handling by reducing the risk of spills, evaporation and airborne contamination in chemical, biotech and analytical workflows. Fabricated from robust PP, the red cap is autoclavable at up to 140 °C and remains dimensionally stable through typical sterilisation programmes. The red colour enables clear visual coding of bottle contents, hazard classes or process steps across the laboratory. Units are packed as 10 pc(s), with a net weight of 0,016 kg per cap. These screw caps from manufacturer Witeg fit standard GL 45 necks and can be used as drop-in replacements within established bottle systems. They suit culture media, buffers, stock solutions and general laboratory liquids where a chemically resistant PP closure, autoclave compatibility and simple colour differentiation are needed in research, teaching or routine quality-control settings.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw caps PP GL 45 red
What is this article?
Screw caps PP GL 45 red 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.
