PROBLEM TO BE SOLVED: To provide an automatic sampler with a balance, capable of replacing samples without applying load to the balance by a simple mechanism and capable of preventing a liquid sample from being directly applied to the balance and the inside of a device.SOLUTION: When measurement is started, a flask rotation plate 6 is rotated, a flask 10 is slid on a flask sliding table 5, moved to a position of a flask holder 7 and placed on the flask holder 7. Then, the flask holder 7 is moved downward, the flask 10 is placed on a scale pan 4, and after measuring the weight of the flask 10, the flask holder 7 is lifted up and the flask 10 is placed on the flask holder 7 again. In the situation, a suction nozzle is inserted into a sample suction position in the flask 10, and when the suction nozzle is pulled out after sucking a liquid sample from the flask 10, the flask holder 7 is again moved downward, the flask 10 is placed on the scale pan 4 and the weight of the flask 10 after sample dispensation is measured. |
