Tamper evident screw cap, GL 45

Tamper-evident closure GL 45 is a polypropylene (PP) screw closure intended for narrow-neck square screw bottles fitted with a high-form GL 45 thread. Finished in blue, the component provides a clear visual and mechanical indication of container integrity for laboratory and process vessels. The polypropylene construction combines chemical resistance with the mechanical strength required for repeated handling of sample and reagent bottles. High-form thread geometry ensures positive engagement with matching GL 45 necks on square bottles commonly used in analytical and research environments. Supplied as a single piece, the closure is ready for immediate fitting to compatible enghalsig Vierkant-Schraubflaschen. Blue colour coding supports rapid identification among other laboratory fittings on the bench or in storage. This tamper-evident closure from manufacturer IDL GmbH addresses secure packaging needs where originality protection is essential during transport, storage and sample handling. The GL 45 standard thread guarantees broad interchangeability with corresponding laboratory bottles, while the robust PP body withstands typical laboratory stresses associated with filling, capping and redistribution of liquids or solids under controlled conditions.
