Laboratory test tube SAFE® 96 XT

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. With patented two-phase TPE compression 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.
