United Scientific® 2D Tubes with Screw Caps, 1.0mL – Internal Thread, 2D Data-Matrix Barcode, Ultra-Low Temperature Storage, 96-Well Rack

The United Scientific® 1.0mL 2D Tubes with Screw Caps are precision-engineered for secure, contamination-free sample storage in demanding laboratory environments. Designed with an internal thread for optimal sealing, these tubes maintain sample integrity even at ultra-low temperatures down to -196°C and during air transport.

Manufactured from virgin medical-grade polypropylene in an ISO Level 8 (Class 100,000) cleanroom, these tubes are certified DNase/RNase and pyrogen free for maximum purity. Each tube features a high-contrast, laser-etched 2D Data-Matrix barcode integrated into the tube body using in-mold labeling, ensuring permanent, chemical-resistant identification that won’t fade, peel, or shed.

The included TPE screw caps with silicone seals provide exceptional leak resistance, while the Twist-Lock rack design prevents tube rotation during capping and decapping, enabling smooth operation in automated systems. These tubes are IATA-compliant for safe air transport and CE certified for use in regulated laboratory environments.

Perfect for biobanking, cryogenic storage, and automated sample tracking, United Scientific® 2D Tubes deliver unmatched durability, accuracy, and reliability.
