Description
Screw cap with lip seal, yellow, GL 45, PP is a polypropylene laboratory closure designed for secure sealing of GL 45 threaded bottles and vessels. The integrated lip seal supports a reliable fit against the bottle neck, helping reduce leakage and evaporation during routine handling, storage, and transport of laboratory media and reagents. Manufactured from polypropylene (PP) in a clear yellow colour, the cap is easy to identify in multi-sample workflows and colour-coded setups. It withstands steam exposure up to 140 °C, making it suitable for steam sterilisation cycles commonly used in laboratory glassware and plasticware preparation. Supplied as a single piece, this GL 45 screw cap from manufacturer lab-o-plastix fits standard laboratory bottles with a matching GL 45 thread and is intended for everyday use in chemical, biological, and general analytical laboratories. The robust PP construction offers good chemical resistance for typical aqueous and many organic laboratory applications while remaining lightweight and easy to handle. Ideal as a replacement cap or as part of a consistent closure system for media bottles, reagent bottles, and sample containers requiring a dependable yellow GL 45 screw closure with lip seal.

Questions about Screw cap with lip seal, yellow, GL 45, PP
What is this article?
Screw cap with lip seal, yellow, GL 45, PP is the article on this page. Luminix Health distributes lab-o-plastix 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.
