Celltreat Centrifuge Tube 50 ml Snap Pop Lid Sterile Case of 500 Tubes

Celltreat 50 mL Centrifuge Tubes with Snap Pop Lid, Sterile (229498) – Case of 500

The Celltreat 50 mL Centrifuge Tubes with Snap Pop Lid (229498) are innovative, high-clarity polypropylene laboratory tubes designed to streamline liquid handling, sample transfers, and high-throughput centrifugation workflows. Unlike traditional screw-cap tubes that require two-handed manipulation or repeated twisting, these tubes feature an ergonomic, attached flip-top Snap Pop lid that can be easily opened and securely closed with one hand. Precision-molded from premium, medical-grade virgin polypropylene, these conical bottom tubes offer high chemical resistance and mechanical strength, making them an ideal consumable for cell culture media preparation, biological sample collection, and high-speed benchtop centrifugation.

Technical Performance & Ergonomic Design

• One-Handed Snap Pop Lid Mechanism: Designed with a hinged flip-top cap that snaps open and closed effortlessly using a single thumb, reducing repetitive wrist strain and speeding up liquid transfers under biosafety cabinets.
• Leak-Tight Compression Seal: Features a precision-engineered seal ring inside the cap that engages firmly with the tube rim, providing a secure, liquid-tight closure during vigorous vortexing and centrifugation.
• High-Clarity Medical-Grade Polypropylene: Molded from ultra-clear virgin polypropylene to provide glass-like visibility of contents, phase separations, and cell pellets.
• High-Contrast Printed Graduations: Outfitted with bold, dark black graduation marks in 2.5 mL increments alongside a large, white write-on marking area for clear sample labeling and tracking.
