摘要： An automatic analyzer has a washing tank providing water for washing a reagent or sample probe is. The washing water from a washing nozzle spreads from a throttle portion and is divided into right and left flows after colliding with a vent plate provided in an overflow portion of the washing tank. The washing water flows between the vent plate and the inner wall of the overflow portion, and the flows join behind the vent plate. After joining, the washing water flows downward along the vent plate and the inner wall of the overflow portion and then is drained. Because a space is created between the washing water which has collided with the vent plate and the washing water joined behind the vent plate, the washing water is prevented from completely covering the overflow portion, and the airflow can be secured during the drainage.

摘要： A needle for forming a cut in a reagent bottle lid is shaped such that an expansion portion which pushes and opens a cut and a piercing portion which forms the cut are integrated with each other. Consequently, only a single operation for moving the needle downwardly will form a cut using the needle and expand the cut using the expansion portion. Further, the smaller diameter of the expansion portion than the diameter of a circumscribed circle of a cross section of the piercing portion but equal to or greater than the diameter of the reagent probe can form cuts uniformly.
