After blood has been collected from the sender, samples are transported to the laboratory in the transport box TriCollect. This is done safely and with complete avoidance of plastic waste. The samples are unpacked in the sample reception area of the laboratory and placed on the intelligent transport system InTrac. The samples are thus continuously fed into the ATRAS. Here the samples are registered with simultaneous plausibility check and subsequent sorting. From the ATRAS, the samples are automatically transported by InTrac to the next workstations.
