## Abstract

A sample is contained in a sample container and a physical relationship between the sample and a sample ID thereof is established. However, after the sample ID is read by a bar code reader and the sample is transferred to an analysis-dedicated small sample container, the sample ID and the sample are separated from each other. Following the end of analysis, therefore, the sample ID must be merged with a corresponding analysis result. A read/write-enable ID carrier is provided on an analysis-dedicated sample container into which the sample is pipetted or on a tank for holding the analysis-dedicated sample container. When the sample is pipetted or when the analysis-dedicated sample container is moved, the sample ID and other information are transferred to the read/write-enable ID carrier.

## Claims

### Claim 1

An analysis apparatus comprising:
a first sample container for containing a sample;
a second sample container for containing a sample;
an information recording medium provided on said first sample container and recording information regarding the sample contained in said first sample container;
a pipetting mechanism for distributing the sample contained in said first sample container into said second sample container;
a transportation mechanism for transporting said second sample container, and
per-step container holding tanks on which said second sample container is successively arranged by said transportation mechanism;
wherein said second sample container includes an information recording medium into which information can be read and written in a non-contact way, being arranged at each of per-step container holding tanks,
said analysis apparatus further comprising a copying mechanism for copying at least a part of the information recorded in said information recording medium provided on said first sample container into a recording medium provided on said each of said per-step container holding tanks on which said second sample container are arranged, when said pipetting mechanism pipettes the same from said first sample container into said second sample container, and said information recorded in said information recording medium provided on said first sample container concerns the sample contained in said first sample container,
said copying mechanism including a function for copying at least a part of the information regarding the sample contained in said second sample container between information recording mediums provided on said pre-step container holding tanks, when said transportation mechanism transports said second sample container between said per-step container holding tanks.

### Claim 2 (depends on 1)

The analysis apparatus according to claim 1,
wherein said per-step container holding tanks include at least one of a pipetting-step container holding tank, a mixing-step container holding tank, a reaction-step container holding tank, and an analysis-step container holding tank.

### Claim 3 (depends on 2)

The analysis apparatus according to claim 2,
wherein said per-step container holding tanks include one of functions of a temperature management function and a stirring function.
