1. A linear movement type reaction treatment apparatus comprising:
a container group in which one or two or more reaction containers and two or more liquid storage portions are arranged in at least one linear shape; a dispensing head to which one or two or more dispensing tips suctioning and ejecting a liquid through a front end insertable into the reaction containers and the liquid storage portions are detachably attached and which is relatively movable between the dispensing tip and the container group in a linear arrangement direction; a magnetic portion which is provided in the dispensing head and is capable of separating magnetic particles contained in a solution inside each dispensing tip by applying a magnetic field into each dispensing tip so that the magnetic particles are adsorbed to an inner wall of the dispensing tip and of separating the adsorbed magnetic particles by removing the magnetic field therefrom so that the magnetic particles are resuspended in the solution; and an ultrasonic vibration device which applies an ultrasonic vibration to a sample storage portion, as the sample storage portion at least one of the liquid storage portions are selected, wherein the container group includes two or more exclusive regions which correspond to two or more sets of dispensing tips respectively so that one set of dispensing tips enters and the other sets of dispensing tips do not enter, wherein at least one reaction container, one or two or more liquid storage portions storing a magnetic particle suspension and a solution necessary for treatment, and one or two or more tip storage portions storing one or two or more dispensing tips in an attachable manner are arranged in a linear shape in each exclusive region, wherein in each exclusive region, at least one scattering prevention lid which is arranged together with the reaction container and the liquid storage portion in the linear shape, and is attached to the opening portion of the sample storage portion by fitting is provided, wherein an upper portion of the scattering prevention lid is formed so as to be attachable to the dispensing head, wherein the scattering prevention lid is attached to the opening portion of the sample storage portion and is detached from the dispensing head so as to be able to close the opening portion, wherein the scattering prevention lid is provided with a film being punchable by downward movement of a punching tip detachably attached to the dispensing head, wherein the ultrasonic vibration device applies an ultrasonic vibration to a sample storage portion, as the sample storage portion at least one of liquid storage portions are selected in each exclusive region, and wherein the opening portion of the sample storage portion is closed with the scattering prevention lid by using the dispensing head, and a target stored in the sample storage portion can be taken out from the sample storage portion, the opening portion of the sample storage portion is closed with the scattering prevention lid after the ultrasonic vibration is applied to the sample storage portion. |
