A reaction tank for causing a reaction for analyzing a specimen in a humidity-applied atmosphere in a storage vessel, includes a humidifying unit that includes a water reservoir reserving water and a humidifier releasing moisture of the water reservoir to an inside of the storage vessel, the humidifying unit humidifying the inside of the storage vessel, and a humidity detector that detects humidity inside the storage vessel. An operation of the humidifier of the humidifying unit is turned ON when the humidity inside the storage vessel becomes lower than a predetermined suitable humidity whereas the operation of the humidifier of the humidifying unit is turned OFF when the humidity inside the storage vessel exceeds the predetermined suitable humidity.
1. A reaction tank for causing a reaction for analyzing a specimen in a humidity-applied atmosphere, comprising:
a storage vessel containing the humidity-applied atmosphere, the storage vessel having a carry-in opening and a carry-out opening, each opening having a respective door operable to be opened and closed;
a humidifying unit that includes a water reservoir reserving water and a humidifier releasing moisture of the water reservoir to an inside of the storage vessel, the humidifying unit humidifying the inside of the storage vessel;
a transport mechanism configured for carrying a microplate holding the specimen into the storage vessel through the carry-in opening and for carrying the microplate out of the storage vessel through the carry-out opening; and
a humidity detector that detects humidity inside the storage vessel,
an operation of the humidifier of the humidifying unit being turned ON when the humidity inside the storage vessel becomes lower than the predetermined suitable humidity whereas the operation of the humidifier of the humidifying unit being turned OFF when the humidity inside the storage vessel exceeds the predetermined suitable humidity,
wherein the reaction tank maintains a predetermined suitable humidity within the storage vessel even when the microplate is frequently carried in and out of the storage vessel.
2. The reaction tank according to claim 1 , wherein
the humidifying unit includes a water replenisher that replenishes water in the water reservoir, and the water replenisher replenishes the water in the water reservoir when the humidity inside the storage vessel becomes lower than a predetermined replenishment humidity.
3. The reaction tank according to claim 1 , wherein
the humidifying unit includes a water replenisher that replenishes water in the water reservoir and a water level detector that detects a water level of water reserved in the water reservoir, and the water replenisher replenishes water in the water reservoir when the water level of the water reserved in the water reservoir becomes lower than a predetermined water level.
