Molded to precise mechanical tolerances from high-purity virgin high-density polyethylene (HDPE), these 20 mL vials feature lightweight, ultra-thin walls that maximize ultraviolet and light transmission while drastically reducing background noise counts. Each vial arrives pre-assembled with a white 22-400 threaded polypropylene screw cap fitted with a resilient, foamed polyethylene (PE) liner. This multi-layer elastomeric lining creates a tight hermetic seal that actively resists chemical attack from aggressive scintillation cocktails, alcohols, acids, and alkalis, preventing hazardous fume escape and concentration drift during high-throughput counting runs.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eLightweight High-Efficiency HDPE Matrix:\u003c\/b\u003e Fabricated from specialty high-density polyethylene characterized by ultra-low background interference and high UV transparency.
