PURPOSE:To hold the tip of a nozzle clean with a small amount of cleaning liquid and to take a high-accuracy analysis by separating a 1st and a 2nd cleaning tank from each other. CONSTITUTION:The 1st cleaning tank 1 which is detachable is provided in the 2nd cleaning tank 2. When the cleaning liquid is discharged from a sampling nozzle 3 inserted into the 1st cleaning tank 1, the cleaning liquid is stored in the cleaning tank 1 by the effect of the contraction part 13 at the tip part of the cleaning tank 1. Consequently, a sample or reagent sticking atop of the nozzle 3 is washed away. Further, the contraction part 13 is clogged, the cleaning liquid 15 overflows from the cleaning tank 1, but it flows out into the 2nd cleaning tank 2 through a relief hole 14 and never enters the device. Further, the 1st cleaning tank 1 where the contraction part 13 is clogged with a solid body can be extracted from the 2nd cleaning tank 2 and the clogging is easily removed. Consequently, the nozzle tip is held clean with a small amount of cleaning liquid and a high-accuracy analysis is capable. |
