Title:
APPARATUS FOR INTEGRATING PROCESSING OF MAGNETIC PARTICLES, AND METHOD OF CONTROLLING THE SAME
Document Type and Number:
WIPO Patent Application WO/1999/047267
Kind Code:
A1
Abstract:
An apparatus for integrating the processing of magnetic particles, capable of carrying out the integrating processing of magnetic particles contained in a fluid with a high accuracy, at a high speed or with a high efficiency, and a method of controlling the same. The apparatus for integrating the processing of magnetic particles comprises a storage unit provided with a plurality of vertical hole type storage sections which are adapted to store a sucked fluid therein, and which have a matrix type arrangement, a sliding body which has a plurality of slidable projections adapted to be moved slidingly in the storage sections and extending downward, and which is provided so that the sliding body can be moved vertically with respect to the storage unit, a plurality of nozzles communicating with the storage sections at lower ends thereof and permitting a fluid to pass through the interior thereof, and a magnetic means provided with a plurality of insert portions having magnetizable and demagnetizable walls, through which the nozzles are inserted, which walls contact or approach outer surfaces of the nozzles and are formed so that they have divisional wall portions spaced from each other so as to have mutually opposite polarities when magnetized.
