ABSTRACT:
An object of the present invention is to carry out the extraction and purification of DNA in a short period of time. This object is accomplished by DNA extraction and purification apparatus illustrated in the drawing. This apparatus includes a pipetting unit which can be horizontally moved along a rail by means of a transfer device. This apparatus also includes tube racks which can be moved horizontally and vertically. In these tube racks are disposed filter tubes (not shown) for the extraction and purification of DNA. Moreover, a waste liquid vat and a recovery vat are disposed below these tube racks. The waste liquid vat and the recovery vat are each provided with a suction port (not shown) to be connected to a vacuum pump.
