Corning Centrifuge Tubes 15 ml with Centristar Cap - Case of 500 Tubes

Corning 430791 15 ml Centrifuge Tubes with CentriStar Caps (Case of 500)

Engineered for high-performance centrifugation and secure sample storage, the Corning 430791 15 ml centrifuge tubes deliver uncompromising reliability for clinical and molecular biology workflows. Manufactured from high-clarity, ultra-pure polypropylene, these tubes withstand significant centrifugal forces and harsh chemical environments without compromising structural integrity. The advanced CentriStar cap features an ergonomic, easy-on/easy-off flat top design that incorporates a specialized internal plug seal, entirely eliminating the risk of leakage during rigorous agitation or long-term archiving. Each tube is sterilized, non-pyrogenic, and certified RNase/DNase-free, guaranteeing an uncompromised environment for sensitive genomic and proteomic samples. Bold, high-contrast printed graduations and a large white marking spot facilitate precise volumetric measurements and durable sample identification. Packaged in a bulk case of 500, these premium tubes ensure consistent, contamination-free processing across high-throughput laboratory operations.

Technical Performance and Design

• CentriStar Plug-Seal Cap: Delivers a superior, leak-proof barrier that prevents sample loss and aerosolization during high-speed centrifugation, vortexing, and hazardous material transport.

• Advanced Polypropylene Construction: Provides exceptional optical clarity for phase separation viewing while offering high tensile strength to withstand extreme relative centrifugal forces (RCF) and broad temperature fluctuations.

• High-Contrast Printed Graduations: Ensures precise volumetric pipetting and rapid fluid level assessments, maintaining visual accuracy even under challenging low-light laboratory conditions.

• Ergonomic Flat-Top Design: Facilitates comfortable, single-handed opening and closing while providing a stable, flat surface for additional top-down marker labeling and rapid sample indexing.
