Description
Screw cap with lip seal, purple, GL 32, PP is a laboratory screw closure for GL 32 threaded bottles and vessels. The purple polypropylene (PP) cap incorporates a lip seal to promote reliable sealing during storage, reagent handling, and routine laboratory operations. Violet/purple colour coding enables fast visual differentiation of samples or process groups, reducing mix-ups where multiple bottle series share the same bench or shelf. Constructed from polypropylene, the cap is intended for typical laboratory service and is stated as resistant to steam up to 140 °C, supporting use where steam exposure remains within that specification. Available as 1 pc, the unit works well for single-cap replacement or for completing colour-coded GL 32 closure sets. This screw cap with lip seal from manufacturer lab-o-plastix matches standard GL 32 laboratory bottle threads used across glass and compatible plastic containers. Colour-coded purple closures are practical in analytical, preparative, and general laboratory settings that depend on clear visual organisation. The lip-seal geometry assists sealing contact on the bottle rim, while the GL 32 thread ensures compatibility with widely adopted laboratory neck formats.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap with lip seal, purple, GL 32, PP
What is this article?
Screw cap with lip seal, purple, GL 32, 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.
