Description
Screw cap LDPE natural GL 40 is a laboratory bottle closure produced from low-density polyethylene for sealing vessels with a GL 40 thread. The natural-coloured LDPE construction gives a flexible yet secure fit suited to routine laboratory bottle handling and sample containment. Low-density polyethylene is widely used for laboratory closures where chemical compatibility and ease of handling are required for everyday workflows. Offered as a single piece, this screw cap from manufacturer lab-o-plastix matches standard GL 40 laboratory bottles used for reagents, buffers and other laboratory liquids. The natural finish allows clear visual inspection of the sealing zone during preparation, transport and storage. Designed for general laboratory applications that need a dependable LDPE screw closure on GL-threaded glassware, it supports consistent bottle management in research, analytical and teaching environments. The GL 40 thread geometry ensures straightforward interchange with compatible laboratory bottles already in use on the bench.

Questions about Screw cap, LDPE, natural, GL 40
What is this article?
Screw cap, LDPE, natural, GL 40 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.
