Abstract: PROBLEM TO BE SOLVED: To provide a nozzle apparatus capable of discharging a liquid containing no bubbles from the nozzle. SOLUTION: A liquid 12 in a cooled state in a liquid tank 10 is injected to a deaeration vessel 14 by an injection pump 28. The deaeration vessel 14 is adjusted to house a proper quantity of the liquid 12 and while the liquid 12 is stored in the deaeration vessel 14, bubbles are formed to move upward to the water surface. Because a discharge port 40 for discharging the liquid is formed on the bottom of the deaeration vessel 14, the bubbles are not incorporated into the discharged liquid 12. The liquid 12 flows into a dispensing pump 46 by the self weight and the dispensing pump 46 supplies the liquid 12 to the nozzle 20 without imparting negative pressure to the liquid 12. As a result, the liquid 12 containing no bubbles is discharged from the nozzle 20.

Abstract: PROBLEM TO BE SOLVED: To solve a problem wherein a self-diagnosis of a conventional dispensation device occurs to overlook a change when a dispensing pump causes operational failure, and when causing a trace quantity of leak in a joining part of a valve of a pipe system and a syringe. SOLUTION: A prescribed quantity of liquid is discharged to a reaction cell 60 from a dispensing nozzle 50. A liquid level of the liquid is detected by using a liquid level detecting electrode 54. The quality of discharge operation is diagnosed on the basis of the detected liquid level. Afterwards, the liquid in the reaction cell 60 is wholly sucked by a cleaning nozzle 80, and then, the liquid level is similarly detected, and the quality of sucking operation is diagnosed from the result.

SOLUTION: Reaction cells of 125 pieces are set on a rotary table, and a plurality of apparatuses are adjacently arranged on the reaction table. When selecting an analyzing method A, the rotary table is rotatably driven with an angle equivalent to one reaction cell as one unit. While, when selecting an analyzing method B, the rotary table is rotatably driven with an angle equivalent to four reaction cells as one unit. Thus, a series of analyzing process is completed by one rotation in the analyzing method A. While, the series of analyzing process is completed by four rotations in the analyzing method B.

Abstract: PURPOSE:To surely perform transfer and input even in case of the preservation state of a bead being in dry and wet states, by forming a double structure in which a pressure reducing pipe and pressurizing pipe of different diameters are provided co-axially respectively and providing a transfer nozzle fixing the bead by suction and releasing by arranged the pressure reducing pipe and pressurizing pipe to the bead attaching port of the tip. CONSTITUTION:A transfer nozzle 2 is made of a double structure with the pressurizing pipe 17 and pressure reducing pipe 10 consisting of two different diameters being co-axial. So at the bead suction time, pressurizing can be executed by a pressurizing pump 11 by a pressure reducing and pressurizing control means, with performing suction by a pressure reducing suction pump 6. Thus, the release of the bead 1 can surely be performed. Also, the reservation liquid accumulated at the tip part of the transfer nozzle 2 inside at the bead 1 suction time is fed onto a pressure reducing pipe 16 upper face or into a trap bottle by pressurizing. By the pressurizing by this pressurizing pump 11, the fall of the reversation liquid left at the tip of the transfer nozzle 2 can be prevented as well as the release of the bead 1.

Abstract: PROBLEM TO BE SOLVED: To prevent the formation of a liquid ball at the point of time of completion of discharge while improving liquid drainage in a dispenser. SOLUTION: The leading end surface 16 of a dispensing nozzle 12 is set to the height separated from a liquid surface 14 by an offset distance Δh at the point of time of completion of discharge. The offset distance Δh is set so as to be not more than the maximum value of the size of the liquid ball formed on the leading end surface 16 of the dispensing nozzle 12. The level of the liquid surface 14 is calculated on the basis of the shape data or the like of a container or actually measured.
