<p>An automatic analyzer includes a sample dispensing unit 102 that dispenses a sample into a reaction vessel, a reagent dispensing unit 106 that dispenses a reagent, a sample nozzle cleaning tank 110 that cleans a nozzle of the sample dispensing unit 102, a reagent nozzle cleaning tank 111 that cleans a nozzle of the reagent dispensing unit 106, a compressor 8 that supplies compressed air, and cleaning water supply means 7 that supplies cleaning water. The tanks 110, 111 each have an upper vent 3 that allows a nozzle 2 to have access for cleaning, a lower vent 4 that drains the cleaning water, a cleaning water jet port 5 that sprays the cleaning water to the nozzle 2, and a compressed air jet port 6 that removes residual cleaning water left on the nozzle 2. The lower vent 4 has an opening area wider than that of the upper vent 3. This provides an automatic analyzer capable of drying the nozzle within a short period of time without allowing the cleaning water to splash outside and making an evaluation with high throughput and high accuracy.</p> |
