Abstract
An automatic analyzer which can remove air bubbles in a photometric light path within a reaction tank and can provide accurate measurement results with stability. The automatic analyzer comprises a reaction cell for mixing a sample and a reagent therein, a constant temperature bath for holding water in which the reaction cell is immersed, a suction pipe for sucking the water in the constant temperature bath, a return pipe for returning the water to the constant temperature bath, a pump disposed between the suction pipe and the return pipe and circulating the water, a heater for heating the water circulated in the constant temperature bath by the pump, and an air-bubble removing unit disposed between the suction pipe and the return pipe, having a water-tight structure to hold the constant temperature bath water therein, and removing air bubbles based on a difference in gravity between the water and the air bubbles.
