The 3.00ml tubes with external thread hybrid guarantee sample traceability, optimize working volume and increase overall sample storage efficiency. The transparent part of the tube walls enable easy visual checking of the sample, while the 4 coding concepts guarantee sample traceability. Samples can be identified with the 2D Data-Matrix, 1D barcode, numeric human-readable and by written codes on the white surface of the tube. The unique combination of coding concepts, and the dimensions of the tubes, make the tubes extremely versatile. The tubes are compatible with ANSI / SLAS format racks, standard cryo boxes, automated stores and liquid handlers. 

Externally threaded tubes also allow for a higher volume of material to be stored inside, which means that sample tubes can hold more while occupying the same amount of storage space. The optimized working volume of the tubes increase the storage capacity of manual freezers and automated stores. 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.
