Abstract
The present application provides a magnetic bead-based nucleic acid extraction apparatus including a well plate, a magnetic attraction mechanism, a position moving mechanism, and an oscillation mechanism, a supporting base, and a fixing base disposed on the supporting base. The magnetic attraction mechanism includes a magnetic bar fixing base and a magnetic bar movably disposed on the magnetic bar fixing base. The position moving mechanism includes a ball screw and a driving motor; two ends of the ball screw are respectively connected to the magnetic bar fixing base and the driving motor. The oscillation mechanism includes a carrier and a main oscillation unit connected to the carrier. The main oscillation unit includes a motor spindle, an eccentric column, and a connecting base.
