Analyzing apparatus

Abstract

An analyzing device includes: an operation cavity that is adjacent to a first reserving cavity retaining a sample liquid, in a circumferential direction of rotational driving; a connecting section provided on a side wall of the first reserving cavity to suck the sample liquid by a capillary force and transfer the sample liquid to the operation cavity; and second reserving cavities that are disposed outside the operation cavity in the circumferential direction of the rotational driving and communicate with the outermost position of the operation cavity through a connecting passage. The connecting section is circumferentially extended farther than the liquid level of the sample liquid retained in the first reserving cavity.

         10 . An analyzing device having a microchannel structure for transferring a sample liquid to a measurement spot by a centrifugal force, the analyzing device being used for reading that accesses a reaction liquid at the measurement spot,
 the analyzing device comprising:   a separating cavity for separating the sample liquid into a solution component and a solid component by using the centrifugal force;   a measuring passage that receives a portion of the solution component separated in the separating cavity and retains the portion of the solution component;   a connecting passage whose proximal end is connected to a bottom of the separating cavity, the connecting passage transferring the sample liquid of the separating cavity;   an overflow cavity connected to an other end of the connecting passage; and   a liquid retaining connecting passage provided from an outlet of the connecting passage in a circumferential direction.
