Biological Material Purification Method, Magnetic Stand, And Biological Material Purification Device

A biological material purification method comprising:

• an adsorption step of charging magnetic beads having a saturation magnetization of 50 emu/g or more, a biological material, and a liquid into a container, adsorbing the biological material to the magnetic beads, and then removing the liquid;
• a washing step of washing, with a wash solution, the magnetic beads to which the biological material is adsorbed after the adsorption step;
• and
• an elution step of eluting the biological material adsorbed to the magnetic beads after the washing step, wherein
• the washing step includes
• a magnetic bead collection treatment of immobilizing the magnetic beads by washing, with the wash solution, the magnetic beads to which the biological material is adsorbed, and then disposing a magnet such that an extension line of an orientation of a magnetic pole does not overlap the container,
• a wash solution discarding treatment of discarding the wash solution in the container in a state in which the magnetic beads are immobilized, and
• a wash solution drying treatment of vaporizing, after the wash solution discarding treatment, the wash solution in a state in which the magnet is disposed such that the extension line of the orientation of the magnetic pole overlaps the container and a magnetic field gradient in the container is 40 T/m or more.
