Embodiment Construction

[0029] Refer below figure 1 The outline of the drainage system of the present invention will be described.

[0030] The liquid discharge system 1 includes a plurality of suction nozzles 2 , a suction nozzle moving device 3 , a magnetic particle containing device 4 , and a solution discharge device 5 . The moving device 3 moves the suction nozzle 2 towards or away from a container 6 such as a microplate assembly. The holding device 4 holds the magnetic particles in the container 6 , thereby preventing the magnetic particles from being sucked out by the suction nozzle 2 . The discharge device 5 causes the suction nozzle 2 to suck the solution out of the container 6 and discharge it into the container 5f.

[0031] The container 6 is not limited to the micro-plate assembly, it can be any other container capable of holding a liquid sample such as a small bottle. Magnetic particles for holding target substances are put into container 6 . In the embodiment of the invention descri...

Abstract

In a system for sucking and discharging a solution from a vessel (micro-plate assembly 6) by suction nozzles 2, processes for suction, discharge, separation, etc. can be carried out with use of a simple mechanism, including suction nozzle moving means 3 for positioning the respective distal ends of the suction nozzles on the inner wall surface of the vessel, magnetic particle holding means 4 for magnetic particles 7 in a given position in the vessel, and solution discharge means 5 for sucking out and discharging the solution simultaneously from the vessel through the suction nozzles. Each or a combination of these means constitutes a drainage system.

Description

technical field [0001] The invention relates to a liquid drainage system, which is used to complete the required treatment in predetermined processes such as reagent addition, liquid suction, liquid discharge, and separation by using a container. Background technique [0002] In the fields of clinical chemistry, biochemistry, pharmaceutical chemistry, etc. including chemical analysis, various processes such as addition of reagents, suction, discharge, and separation of liquids are performed during the reaction process. For example, in the case where a target substance is contained in a liquid sample contained in a container such as a microplate assembly or a vial, magnetic particles for holding the target substance on their respective surfaces are added to the liquid sample. After the target substance is held on the surface of the magnetic particle, the supernatant is sucked and discharged, whereby the target substance can be separated from the liquid sample. [0003] In th...
