Abstract
A constant-temperature air type automatic analysis apparatus includes: a reaction table for rotating a row of reaction containers; a batch injecting device for supplying a sample and a reagent into the reaction containers; a photometric device for measuring a reaction within the reaction containers; a constant-temperature air device for keeping the reaction containers warm, the constant-temperature air device having an annular constant-temperature air chamber which is formed in such a manner as to surround the row of reaction containers; a heat block disposed within the annular constant-temperature air chamber; and a preliminary temperature raising device for heating the reaction containers. The preliminary temperature raising device has an air circulation passage, a blowing device for blowing a constant-temperature air against the reaction containers in a region between a injection position of the batch injecting device and a measuring position of the photometric device. Alternatively, the preliminary temperature raising device has a ventilating device for temporarily ventilating the air circulation passage.
