Patent ID: 8163183

Claim:
A magnetic particle parallel processing apparatus permitting repeated use of a container, comprising: at least one reaction container capable of storing a liquid to be processed; a liquid disposal tank capable of storing a liquid to be disposed or allowing the liquid to pass through; a reagent feeder with at least one flow channel for feeding at least one type of liquid selected from the group consisting of two or more types of solutions and a magnetic particle suspension according to the processing content, at a given amount and at a given timing, to said reaction container; and a magnetic separator which has at least one processing nozzle with a distal end insertable into said reaction container and said liquid disposal tank, for sucking and discharging a liquid through said distal end, and which also has a magnetic means capable of applying a magnetic field to the interior of the distal end to thereby attract magnetic particles contained in the liquid inside the distal end to the inner wall thereof to effect separation of the magnetic particles, and canceling the magnetic field to thereby release the attracted magnetic particles and re-suspend the same in a liquid, wherein the distal end of said processing nozzle is relatively movably provided between said reaction container and said liquid disposal tank, said flow channel has a distal end insertable into said reaction container, the solutions and the magnetic particle suspension are discharged through the distal end, and the distal end of the flow channel is relatively movably provided with respect to the reaction container, and when the distal end of the processing nozzle is moved to a position where it is insertable into the liquid disposal tank, the distal end of the flow channel can be moved to a position where it is insertable into the reaction container while the distal end of the processing nozzle remains in the position where it is insertable into the liquid disposal tank.
