The invention provides a device (10) for feeding sample containers (18) with an analysis sample (P) to be treated, to a treating apparatus (12) for treating the analysis sample (P), in particular to a centrifuge. The device comprises a conveyer (26, 27) for conveying at least one sample container (14) or at least one carrier containing a sample container (14), wherein the conveyer (26, 27) is configured for receiving multiple sample containers (14) and/or carriers and forms a circulating endless conveyer track. The device further comprises an input station (18) for handing over a sample container (14) or a carrier to the conveyer (26, 27). The input station (18) is displaced (V1, V2), with respect to the conveyer (26, 27), obliquely to the conveying direction (26b, 27b) Hof the conveyer (26, 27). A removal station (20) is for removing the sample container (14) or the carrier out of the conveyer (26, 27), and a transfer device (44) serves for removing the sample container (14) or the carrier with the sample container (14) out of the conveyer (26, 27) for further transport to the treating apparatus (12) and for a hand over to the conveyer (26, 27) after the treatment of the analysis sample (P) of the sample container (14) in the treating apparatus. An identification unit (48) is provided for identifying a sample container (14).
