The present invention relates to novel modules for transferring magnetic beads, an automated system comprising the same and a method for extracting nucleic acids using the same. The specifically designed magnet module and cover module of the present invention can be employed in the automated liquid handling apparatus by means of pre-existing moving modules (e.g., pipettor module) of the apparatus. The present invention enables a bead transfer-type method for extracting nucleic acids to be performed in an automated manner on the automated liquid handling apparatus. The present invention provides advantages of higher level of automation, more reduced cost and no need for another separate liquid handling apparatus compared to the conventional bead transfer-type method usually performed in the small apparatus designed to be used only for this bead transfer-type method. Also, the present method has the merits of more shortened reaction time compared to the conventional liquid transfer-type method.
