Description
Screw cap PP, blue, GL 45 is a laboratory bottle closure manufactured from polypropylene for a tight, reliable seal on GL 45 laboratory bottles. Large external ribs improve grip and allow fast opening and closing even when gloves are worn. The blue colour coding supports quick visual identification of bottle contents in multi-sample workflows. Each cap is supplied with a clear O-ring to help maintain a secure seal during storage and handling. Available as a pack of 10 pieces from manufacturer ISOLAB Laborgeräte, these caps suit media bottles, reagent bottles and other GL 45-threaded laboratory containers used in chemistry, biology and quality-control laboratories. The polypropylene body offers chemical resistance appropriate for everyday laboratory solvents and aqueous solutions under normal conditions. Colour-coded options in the same series include red, yellow and green, enabling simple content differentiation across a bench or storage shelf. Practical for teaching labs and research groups that need consistent, easy-to-handle GL 45 closures without complex sealing systems.

Questions about screw cap - GL 45 - P.P - blue
What is this article?
screw cap - GL 45 - P.P - blue is the article on this page. Luminix Health distributes ISOLAB 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.
