Cleaning separation and resuspending device for magnetic particles

The utility model discloses a cleaning separation and resuspending device for magnetic particles, belonging to the field of cleaning separation of magnetic particles. The device comprises a cleaning separation region I, a resuspending region I, a cleaning separation region II, a resuspending region II, a fixed strip, aspirating needles and cleaning needles, wherein the cleaning separation region I is a front section magnet array; the resuspending region I consists of three suspending magnets; the cleaning separation region II is a rear section magnet array; the resuspending region II consists of three suspending magnets; and the cleaning separation region I, the resuspending region I, the cleaning separation region II and the resuspending region II are sequentially fixed on the fixed strip. According to the cleaning separation and resuspending device for the magnetic particles, by virtue of the resuspending of a reversing magnetic field, the cleaning efficiency and quality are improved, and a light emitting reaction is more accurate and sensitive.
