However, in the prior art of this structure, the operation is troublesome in the case of the method of changing the cylinder volume. Further, in the case of the method of changing the liquid sending time, there is a problem that the discharge amount changes due to the change over time of the tube provided in the tube pump, and an error occurs due to this factor. In addition, the dispensing amount may be exceeded due to overrun of the tube pump after the liquid feeding is stopped, or the dispensing amount may be changed due to the pressure change due to the blocking of the liquid feeding flow path. Therefore, an object of the present invention is to provide a solution dispensing device which is easy to operate and can cope with changes with time of a tube pump, etc., and which can obtain a highly accurate dispensed amount even in intermittent operation of liquid feeding. That is.

Therefore, in this solution dispensing apparatus, in each liquid feeding / dispensing operation, the liquid feeding amount from the tube pump is converted into the required storage time by the constant volume weighing means,
This determines the dispensing time. As a result, it has become possible to accurately secure a predetermined dispensing amount by changing the dispensing time in response to the change in the liquid delivery amount due to the aging of the tube pump and the like. Further, even if an overrun occurs in the tube pump here, the closing operation of the valve means has priority over the overrun, so that this problem is also solved. Further, since the conveying means takes charge of the liquid feeding operation on the downstream side of the constant volume weighing means, it is not necessary to adopt a tube pump having a large discharge pressure,
As a result, it is possible to reduce the influence of pressure fluctuations caused by blocking the liquid supply passage. In the end, a solution dispenser was obtained that can stably dispense a reagent solution for a long period of time without being affected by the aging of the tube pump. Further, if the relationship between the storage amount of the constant volume weighing unit and the dispensing amount is stored in memory for each reagent solution, for example, dispensing of plural kinds of volumes can be easily selected.

Now, the tube pump TP is kept in operation during the initializing process P1 and the dispensing process P2. Then, in the initializing step P1,
The first three-way solenoid valve SV1 and the two-way valve SV2 operate alternately according to the detection of the liquid level detection sensor VM. Here, as described above, since the liquid level detection sensor VM is fixed to the upper region of the cylinder part 4, the volume of the cylinder part 4 below the liquid level detection sensor VM is a constant volume. The time required for the reagent solution to accumulate at the site (the time from the opening operation to the closing operation of the first three-way solenoid valve SV1) is the required storage time T1. In the example, this measurement is repeated 5 times. In this state, since the second three-way solenoid valve SV3 is closed, the reagent solution is returned to the tank 2 side via the second return path RL2. By the way, the above-mentioned control device 7 incorporates an arithmetic device 8 as an arithmetic means. The arithmetic unit 8 stores the required storage time (in the embodiment, the above-mentioned 5) from the relationship between the predetermined dispensing amount required for the reagent dispensing unit 3 and the above-described storage amount (constant volume amount of the cylinder portion). The dispensing time T2 is determined based on the average T1 of the measurement results of the times. Then, the first three-way solenoid valve SV1 is opened in the dispensing step for the dispensing time T2.
