VWR Centrifuge Tube 1.5 ml Free Standing Screw Cap Polypropylene 1000 Tubes

VWR 1.5 mL Graduated Microcentrifuge Tubes (16466-046)

The VWR 16466-046 is a high-performance 1.5 mL microcentrifuge tube engineered for high-integrity sample preparation, centrifugation, and long-term cryogenic storage. Manufactured from medical-grade, high-clarity virgin polypropylene, these tubes are designed to withstand high-speed centrifugal forces without leaking or cracking. The integrated snap-cap features a pierceable center and provides a liquid-tight seal that remains secure even during boiling or thermal cycling. With clear, molded-in graduations and a frosted writing surface, the 16466-046 offers the reliability and precision required for sensitive molecular biology, clinical diagnostics, and proteomics workflows.

Technical Performance and Design

• High-Force Centrifugation: Engineered with reinforced walls to withstand high RCF (Relative Centrifugal Force) ratings, making them suitable for DNA/RNA pelleting and protein precipitation.

• Secure Snap-Cap Design: The precision-molded cap provides a tactile "click" ensuring a leak-proof seal, protecting samples from evaporation and accidental opening during agitation.

• Excellent Clarity & Graduations: The ultra-clear resin allows for easy visual monitoring of pellets and liquid interfaces, supported by easy-to-read graduations at 0.1, 0.5, 1.0, and 1.5 mL.

• Frosted Identification Area: Features a large frosted side-wall area and a flat frosted cap, providing a reliable surface for permanent markers and simplified sample tracking.
