Abstract
The utility model discloses a magnetic head assembly to a nucleic acid extraction instrument with magnetic head assembly is disclosed, including magnetic frame and many magnetic rods, the magnetic frame is used for this body coupling with nucleic acid extraction instrument. All the magnetic rods are arranged on the magnetic frame, the lower end heads of the magnetic rods are in an inverted round table shape or a conical shape, the lower ends of the magnetic rods can be inserted into the magnetic rod sleeves, and the outer surfaces of the lower end heads can be close to the inner conical walls on the lower ends of the magnetic rod sleeves. Because the lower end is in an inverted round table shape or a conical shape, the air magnetic resistance of each position of the outer surface of the lower end is similar to that of each position of the outer conical wall of the magnetic rod sleeve, namely the magnetic force of each position of the outer conical wall of the magnetic rod sleeve is similar, the magnetic rod can enable the magnetic beads in the sample solution to carry the nucleic acid to be attached to the outer conical wall of the lower end of the magnetic rod sleeve, the loss of the magnetic beads and the nucleic acid during transferring the magnetic beads is reduced, the bead obtaining rate is improved, the concentration of the nucleic acid is higher, and the detection of the nucleic acid is facilitated.
