Abstract

This invention provides an apparatus for extracting nucleic acids from nucleic acid-containing samples, particularly biological samples, and more particularly to a nucleic acid extraction apparatus well suited for the nucleic acid extraction method utilizing a nucleic acid-binding magnetic carrier. The nucleic acid extraction apparatus of the invention comprises (1) a group of extraction vessels each comprising a reactor tube in which a sample, a reagent solution, and a magnetic carrier are admixed and reacted, a drain cup for pooling an unwanted component solution, and a nucleic acid recovery tube all as secured to a support, (2) a distribution means for introducing a solution into each of the extraction vessels, (3) a stirring means for mixing the solution and magnetic carrier in the reactor tube, (4) a holding means for holding the magnetic carrier stationary within the vessel, (5) a discharging means for discharging the solution from the reactor tube while the magnetic carrier is held stationary, (6) a heating means for heating the solution and magnetic carrier in the reactor tube, and (7) a transfer means for serially transferring the vessels to the given positions where the distribution means, stirring means, holding means, discharging means and heating means are respectively disposed.
