Description
DURAN® tamper-evident cap is a polypropylene screw closure for laboratory bottles with DIN 168-1 / GL 45 thread, designed to show at a glance whether a bottle remains originally sealed. On first tightening, a plastic ring locks firmly over the bottle neck; when the cap is opened the perforation tears and the ring stays on the neck as a clear integrity indicator. After the initial opening the cap continues to function as a standard screw closure. A lip seal with PTFE-coated silicone gasket provides a reliable seal. Compatible with all GL 45 threads, the closure from manufacturer Duran/DWK Life Sciences supports versatile use across bottle systems. Typical applications include liquid transfer between containers, long-term sample storage and archiving, and connection to spinner flasks and cell-culture vessels. The polypropylene construction combines chemical resistance with practical handling for routine laboratory bottle sealing where tamper evidence is required.

A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
