Precision-molded from premium, high-density virgin polypropylene, these 15 mL conical tubes exhibit high chemical resistance across range of acids, bases, and organic solvents. The system integrates a traditional, ribbed **polyethylene plug seal cap** that provides a gas- and liquid-tight mechanical compression fit to completely suppress fluid weeping or sample aerosolization under extreme centrifugal forces. Arriving as a commercial facility case of 500 tubes organized in space-saving bulk bags of 50, this sterile, single-use configuration is standard hardware for high-throughput cleanrooms, biochemistry lines, and diagnostic biobanks.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Material Architecture\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-G Mechanical Rating: Advanced structural molding enables the conical polypropylene base to withstand physical acceleration stresses up to 12,000 x g (RCF) inside balanced fixed-angle or swinging-bucket centrifuge rotors, avoiding structural fracturing.\u003c\/li\u003e\n\u003cli\u003eDeep-Molded Plug Seal Cap Geometry: Outfitted with an orange, high-density polyethylene (HDPE) screw cap featuring an interior cylindrical plug seal. This seal extends down into the tube neck, creating a tight dual-surface boundary that prevents evaporation and leakage under intense deep-freeze or vacuum conditions.\u003c\/li\u003e\n\u003cli\u003eHigh-Contrast Volumetric Markings: Printed with highly legible, dark black ink graduations running from 1.5 mL up to 14.5 mL in precise 0.5 mL increments.
