Description
Screw cap, LDPE, natural, GL 65 is a laboratory screw closure made from low-density polyethylene (LDPE) in a natural colour and configured for GL 65 threaded bottles and containers. LDPE offers a flexible, resilient sealing behaviour that is well suited to everyday laboratory bottle work, sample storage and transfer operations where a soft yet secure screw fit is preferred. This natural LDPE screw cap is supplied as one piece and is intended for GL 65 necks commonly found on larger laboratory bottles and vessels. From manufacturer lab-o-plastix, the closure provides a straightforward natural-finish option for general laboratory use without introducing coloured pigments into the sealing component. Low-density polyethylene is valued in labware for its toughness, chemical resistance profile typical of polyolefins and ease of handling when opening and closing bottles repeatedly. The GL 65 thread ensures dimensional compatibility with matching bottle necks, supporting a stable seal for aqueous solutions, buffers and many routine reagents. Choose this natural LDPE GL 65 screw cap when a flexible polyethylene closure in an uncoloured appearance is required for laboratory bottles, storage vessels or process containers that use the GL 65 standard.

Questions about Screw cap, LDPE, natural, GL 65
What is this article?
Screw cap, LDPE, natural, GL 65 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.
