1 mL Storage Tube (External Screw Cap, Sterile)

MCE Storage Tube, also known as 2D-coded sample tubes, feature an external thread and external screw cap design and are compatible with sample tube racks conforming to SBS (Society for Biomolecular Screening) standards, such as the SBS-format Sample Storage Rack (MCE Cat. No.: HY-KM0018).

MCE Storage Tube is manufactured from high-quality PP (polypropylene), offering excellent low-temperature resistance and mechanical strength for long-term sample storage under ultra-low-temperature conditions. Manufactured under stringent quality control, the tubes are free of DNase, RNase, and pyrogens, making them suitable for applications requiring high sample cleanliness. The tubes feature a unique identification system consisting of a 2D barcode on the bottom, a linear barcode on the sidewall, and a human-readable numeric code. All three codes are uniquely matched to the same tube. The codes are laser-etched onto the tube surface, providing excellent resistance to abrasion and scratching. Their high contrast ensures easy identification and reliable scanning, supporting automated sample management, sample identification, and end-to-end traceability.

MCE Storage Tube is available in both non-sterile and sterile configurations to meet the requirements of different sample storage applications.

Features of MCE Storage Tube

1. Laser-Etched Identification Codes: The 2D barcode, linear barcode, and numeric code are laser-etched for excellent abrasion and scratch resistance. The high-contrast codes are easy to identify and scan and are resistant to wear and detachment.

2. Uniquely Matched Three-Code System for Sample Traceability: The 2D barcode on the tube bottom, linear barcode on the sidewall, and human-readable numeric code are uniquely matched to each tube, helping minimize sample mix-ups and supporting standardized sample management and audit traceability.

3. Suitable for Ultra-Low-Temperature Storage: The tubes have undergone performance testing across a temperature range of −196°C to 121°C. Made from high-rigidity, toughened PP, they offer excellent resistance to low temperatures and temperature fluctuations, making them suitable for ultra-low-temperature sample storage.

4. High Cleanliness and Radiation Sterilization Compatibility: The tubes are free of DNase, RNase, and pyrogens and are compatible with radiation sterilization, meeting the requirements of different sample storage and laboratory applications.

5. Optimized Sealing Design to Reduce Over-Tightening: A non-silicone sealing structure combined with a specially designed thread helps reduce the risk of over-tightening the cap, facilitating convenient and consistent handling.

6. Same-Material Tube and Cap: The tube and cap are manufactured from the same material, helping minimize differential expansion and deformation caused by differences in thermal expansion during repeated freeze-thaw cycles and thereby supporting reliable sealing performance.

7. Direct 2D Barcode Reading Within the Rack: The 2D barcode on the bottom of the tube can be read without removing the tube from the rack, improving the efficiency of sample identification and information capture. The tubes are compatible with standard SBS-format racks and are suitable for automated sample storage systems.

8. External Screw Cap for Maximized Usable Volume: The external screw cap design minimizes the space occupied by the cap within the tube, providing greater usable working volume for sample storage and subsequent laboratory applications.
