To accommodate the trend to store samples in cryogenic temperatures, the 1.40ml tubes with external thread have a sturdy design and thick tubes wall – excellent properties for ultra-low temperature storage. Using externally threaded storage tubes eliminates the possibility of the sample coming into contact with the screw thread, minimizing chance of cross-contamination while improving sample integrity. The triple thread of the 1.40ml tubes gives an excellent closure and horizontal placement of the cap to ensure long-term sample preservation and storage. The code surface of the tubes with external thread features a raised edge, which protects the 2D code against accidental scratches, ensuring absolute traceability. The 1.40ml tubes also are available as non-coded offering a cost-effective solution without compromising sample quality and safety.
