Thermo Scientific EZ Flip Conical Tube 50 ml Case of 500 Tubes

Thermo Scientific Nunc 50 mL EZ Flip Conical Centrifuge Tubes, Sterile (362697NS) – Case of 500

The Thermo Scientific Nunc 50 mL EZ Flip Conical Tubes (362697NS) are high-performance, ergonomic liquid handling consumables designed to streamline cell culture workflows, sample preparation, and high-throughput centrifugation. Featuring an innovative attached flip-top cap, these tubes allow researchers to open and close the vessel with a simple one-handed thumb motion, eliminating the need to unscrew traditional caps or place contaminated closures on cleanroom surfaces. Molded from premium, high-clarity virgin polypropylene, these 50 mL conical tubes provide high mechanical strength and exceptional chemical compatibility, making them an essential tool for aseptic transfers inside biosafety cabinets, biological sample collection, and high-speed benchtop centrifugation.

Technical Performance & Ergonomic Design

• One-Handed EZ Flip Cap Design: Outfitted with an integrated hinged flip-top closure that enables fast, one-handed opening and closing to reduce hand fatigue and prevent cap contamination.
• Leak-Resistant Compression Seal: Precision-molded seal ring ensures a tight, leak-resistant closure that protects samples during sample mixing, vortexing, and transport.
• High-Clarity Virgin Polypropylene: Extruded from optical-grade polypropylene, allowing clear, distortion-free monitoring of sample volumes, cell pellets, and interface boundaries.
• Bold Printed Graduations & Writing Area: Features high-contrast black graduation markings across the tube body alongside a large, white write-on panel for easy sample identification and labeling.
