Description
Screw cap with PE liner DIN 45 is a laboratory screw closure fitted with an integrated polyethylene liner for bottles and containers that use a DIN 45 neck finish. The PE insert creates a reliable contact seal that supports secure storage and transport of samples or reagents in everyday laboratory practice. This item belongs to the established groups of screw closures, screw caps and originality closures used across analytical, preparative and quality-control workflows. Supplied as a single piece from manufacturer IDL GmbH, the cap is ready for immediate use as a replacement or spare component. Its standardised DIN 45 thread ensures compatibility with matching laboratory glassware and plastic vessels commonly found in research and industrial settings. The polyethylene liner contributes to a tight fit without requiring separate sealing discs, simplifying handling during routine capping operations. Technicians can apply or remove the closure quickly by hand, supporting efficient sample preparation and storage sequences. The straightforward design makes the Screw cap with PE liner DIN 45 a practical choice for maintaining closed systems in chemistry, biology and related laboratory environments where consistent sealing performance is required.

Questions about Cap DIN 168, made of black molded plastic, with PE insert, DIN 45
What is this article?
Cap DIN 168, made of black molded plastic, with PE insert, DIN 45 is the article on this page. Luminix Health distributes IDL GmbH 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.
