摘要： PROBLEM TO BE SOLVED: To prevent the deterioration of dispensing accuracy when bubbles are generated in a pressure transmission liquid in a dispenser. SOLUTION: A switching valve 8 is provided in the pipeline between a nozzle 2 and a syringe pump 12. A storage tank 30 is arranged at the tip of a pipeline 32 extending upward from the valve 8. Washing liquid, which is the pressure transmission liquid, is sucked into the syringe pump 12 from the side of the nozzle 2. The switching valve 8 is switched, the syringe pump 12 performs the sucking and discharging actions and the washing liquid is moved back and forth between the syringe pump 12 and a washing liquid tank 36. In the storage tank 30, the probability of the approach of the respective bubbles to the surface of the washing liquid becomes high. The bubbles reaching the liquid surface is trapped with an air layer 40 and disappered. Thus, the washing liquid, wherein the bubbles are removed in this way, is returned to the syringe pump 12. The dispensing is performed by using the washing liquid.

摘要： PROBLEM TO BE SOLVED: To provide a pipette device capable of vigorously discharging liquid at the time of starting discharging the liquid by overcoming liquid resistance and accurately controlling discharging force at the time of finishing discharge of the liquid. SOLUTION: A piezoelectric element 22 is disposed in a piston 4 capable of moving in a cylinder 2. When voltage is applied to the piezoelectric element 22, the piezoelectric element 22 extends in directions in which the piston advances and retracts. In a first stage of discharge an acting force to a switch lever 50 is transmitted to a piston shaft 8 through a coil spring 58, and the piston 4 moves forward in the cylinder so that a high discharging force corresponding to a considerably large stroke is obtained. In a second stage of discharge which corresponds to a finishing stage of the discharge, advancing movement of the piston 4 is blocked and the switch lever 50 presses the coil spring 58 to be inserted into the piston shaft 8, and a switch 56 is turned on to apply voltage to the piezoelectric element 22, which then extends to make a head face 12 advance. By using an accurate and fine extension of the piezoelectric element 22, quantity of discharge is accurately and finely controlled.

摘要： PROBLEM TO BE SOLVED: To correctly discharge a sample from a pipette device and prevent air bubbles from being discharged. SOLUTION: A pressure sensor 32 measures a pressure in a nozzle chip 10. A pressure change-analyzing part 36 detects a minimal point of the pressure formed by a pressure drop when a sample is discharged and a pressure rise when air bubbles grow subsequently. The analyzing part 36 outputs a signal to a pump control part 38 at the minimal point as a sample discharge termination timing. Upon receipt of the signal, the pump control part 38 stops pressuring of a syringe pump 6 by a motor 30. The minimal point is detected by detecting a zero cross point from a negative pressure to a positive pressure in a time differential waveform.

摘要： PURPOSE:To present solution from remaining on a tip of a chip to obtain a dispenser with improved accuracy. CONSTITUTION:When a predetermined amount of liquid sample has dripped from a tip of a chip 14, a piston 10b of a syringe pump 10 is pulled down to have suction performed, whereby liquid sample which may possibly remain is dripped down to prevent liquid from becoming a liquid ball at the tip of the chip 14. Thus liquid sample residue on the tip of the chip 14 can be prevented to improve measurement accuracy.

摘要： PURPOSE:To detect not only complete closure of a nozzle but also incomplete closure in a separate injector for dispensing sample by a nozzle. CONSTITUTION:Pressure of an air hose 12 connected to a nozzle 10 for sucking sample 18 is detected by a pressure sensor 20, and the detected value is sent to a closure detection part 26. In the closure detection part 26, a plurality of pressure calculation periods are set, and pressure difference in each calculation period has been calculated. When the pressure difference exceeds a predetermined threshold corresponding to a calculation period in each calculation period, closure is alarmed. Since a plurality of pressure calculation periods have been set, not only complete closure but also incomplete closure can be detected to improve dispensing accuracy.

摘要： PURPOSE:To enable a suction time to be reduced when sucking the red cell constituent which is a highly viscous liquid sample. CONSTITUTION:When sucking a red cell constituent by a nozzle chip, a piston is pulled to the maximum, suction is started by generating a maximum suction force, the piston is returned to a target amount of suction when a pressure of the suction system reaches a certain value alpha, and then the target amount of suction is made finally. Since the suction force of a pump can be utilized to the maximum, suction can be speeded up.

摘要： PURPOSE:To prevent errors in distributing amounts caused by the formation of bubbles and to make analysis and inspection highly accurate by detecting bubbles when the bubbles are formed by the mixing of air when a chip is inputted into a sample in an automatic distributing apparatus which is used for inspecting the samples such as serum, urine, reagent and the like, and stopping the analysis and the inspection of the chip. CONSTITUTION:Near infrared-rays from a near infrared-ray emitting diode 16 is condensed to a certain size in the axial direction of a chip 10 by using a lens 18 and a circular cylinder lens 20. Thus the near infrared rays are inputted. Only the light which has transmitted through this position is inputted into a photodetector 26 through an optical filter 24. At this time, the vacant chip 10 is moved in the direction of an arrow at a constant speed. The amount of the near infrared-rays transmitted through this position is detected with the photodetector 26. The result is stored in a first level memory 34. Then, the chip 10 in which liquid sample is inputted to as not to form bubbles is further moved. The light is detected with the photodetector 26, and the result is stored in a second level memory 36. The amounts of the transmitted light rays stored in the memories 34 and 36 are subtracted in a subtractor 38. The result is compared with a reference value in a reference value memory 42 in a comparator circuit 44.

摘要： PURPOSE:To eliminate the influence of the reflected light by inclining one of a sample vessel, a 2nd filter and a photometric part at an arbitrary angle with the optical axis for irradiation of the luminous flux from a light source. CONSTITUTION:The respective constituting members of the heat ray filter 12, the measuring vessel 16, a BPF 20, and a detector 24 are inclined at the prescribed angle (inclination C) with the optical axis 10a for the irradiation of the luminous flux. The reflected light can be released to the outside of the optical axis 10a for the irradiation of the luminous flux like the reflected light B if the reflection of the incident light or transmitted light of the luminous flux arises at the point of the time when the incident light or transmitted light of the luminous flux arrives respectively at the filter 12, the vessel 16, the BPF 20, and the detector 24. Since the reflected light B is not returned onto the optical axis 10a for the irradiation of the luminous flux, the exact measurement is carried out without being affected by the reflected light B of the transmitted light to be detected. The influence of the light is surely prevented by inclining the respective constituting members.
