A system is disclosed. The system includes an aliquotter module. The aliquotter module includes a track including: a travel lane; a first loop; and a second loop configured to transport sample carriers with primary sample containers. The aliquotter module can further include a pipettor that can aspirate a first aliquot volume of a sample in a primary sample container located in an aspiration position and dispense the first aliquot volume of the sample in a secondary sample container located in a dispensing position. The aliquotter module can cause the secondary sample container to leave the aliquotter module before the primary sample container.
