An apparatus for washing magnetic particles including a well plate for receiving an array tube holder having x rows of tubes, each tube containing magnetic particles, the well plate having (x+1) rows of wells for enabling the array tube holder to be shifted from a first position to a second position. The apparatus also includes ((x/2)+1) rows of magnets asymmetrically positioned within the well plate adjacent to the rows of wells. Placing the array tube holder in the first position causes magnetic fields produced by each magnet to attract the magnetic particles in the x rows of tubes to one side of each tube, and shifting the array tube holder to the second position reverses the magnetic fields, causing the magnetic particles to stream across to the other side of each tube. The array tube holder may be a 96 tube array tube holder (8 rows by 12 columns) in which case, the well plate includes 108 wells (9 rows by 12 columns) for simultaneously washing 96 tubes.
