System for pretreating sample

A sample pretreatment system comprising:

• a test tube containing a primary sample and having barcode information thereon;
• a pipetting device configured to pipette one or more aliquot samples from the primary sample contained in the test tube;
• a barcode reader configured to read the barcode information on the test tube;
• and
• a control device connected to the pipetting device and the barcode reader,
• wherein the control device stores minimum guaranteed volume information for each of a plurality of types of test tubes, the minimum guaranteed volume information indicating the minimum volume of sample guaranteed to be contained in the corresponding type of test tube,
• wherein the control device is programmed to:
• control the barcode reader to read the barcode information from the test tube,
• determine the type of the test tube based on the barcode information read by the barcode reader,
• determine the minimum guaranteed volume based on the type of the test tube,
• read in pipetting request information from a computer, the pipetting request information including a volume amount of each of a plurality of aliquot samples to be pipetted for the primary sample,
• determine a combination of aliquot samples of the plurality of aliquot samples in the pipetting request information to be pipetted from the primary sample contained in the test tube such that the cumulative volume of each of the volumes of the combination of the aliquot samples does not exceed the minimum guaranteed volume of the test tube, and
• control the pipetting device to only pipette the aliquot samples of the determined combination of the aliquot samples into respective aliquot sample containers.
