Biobanking, compound management, cryopreservation, population studies, transfusion medicine – the possible applications for high-quality long-term storage of biomaterials in the microlitre scale are growing continually. But if you store large quantities of small samples in the medium to long term for purposes of research and diagnosis, you generally have to deal with various requirements regarding the sample container to be used – from handling to storage through to the follow-up of the respective sample. The overriding priority is the best possible conservation of sample quality and quantity.

This means that three things need to be guaranteed for the samples to be stored: Security, identifiability and space-saving storage. In addition, if automated processability is used in the laboratory, there is no better alternative for modern sample storage.

Storage down to -196°C
SAFE® offers a large range of 2D coded tubes preferably arrayed in space-saving and automated SBS racks that are suitable for storage down to -196°C (LN2). Our product range also includes the required technical infrastructure such as scanners and cappers/decappers. 

External thread (SBS 96)SAFE® 96 XT:
2D tubes with external threads in the 96 SBS format. Especially when it comes to sample storage in automated storage systems, for reasons of costs, it is essential that the largest possible quantity of samples can be stored in a smallest possible space. This is where tubes with external threads have the edge over tubes with internal threads due to their lower height. The SAFE® SX 300 in particular – with an effective working volume of 300 µl and its minimal height of 19.1 mm (incl. screw cap) – is a real miracle of compactness. And the XSX 220 is even more compact with a height of only 15.5 mm.Another advantage of the external thread tubes: Depending on the application, the risks of cross-contamination can be minimised. Furthermore, there is no need to accept the disadvantages in terms of leak-tightness compared to the conventional solutions with internal threads due to the special, patented two-phase TPE compression. On the contrary, due to the two contact phases for the sealing of the liquid phase and a potential gas phase, this screw cap results in the very best sealing characteristics for safe, long-term sample storage.

Internal thread (SBS 96)SAFE® 96 IT:
2D tubes with internal threads in the 96 SBS format. The injected TPE compression ring in the screw cap combined with the widened mouth of the tube and significantly improved sealing compared to the conventional screw caps with an O-ring. The screw cap cannot be overtightened, the permanently injected sealing ring cannot detach itself from the thread. The high screw cap is a big plus for manual handling.
