PROBLEM TO BE SOLVED: To provide an analyser provided with a sampler capable of reading bar codes of a large number of containers as compared with a conventional one and allowing the replacement of the container without causing loss of measurement time. SOLUTION: The sampler 1 is composed of a sampler 5 having a rotation shaft 3 and a sampler 7 coaxially disposed inside and having a rotation shaft 4. The samplers 5 and 7 hold plural containers 15 and 17 in their circumferences, respectively. The bar codes 11 are stuck to the containers 15 and 17. A slit 9 is formed in the sampler 5, and the bar codes 11 can be read by controlling the rotation of the sampler 5 so as to set the slit part 9 at a reading position of a bar code reader 10. The samplers 5 and 7 are journaled to the shafts 3 and 4, and driven and rotated independently of each other by a driving device and a driving control device not shown in the figures.
