Abstract
Disclosed herein is a single-use extraction apparatus which is disposed of after use. The extraction apparatus includes a tube plate having a tube therein, and a column plate. The column plate is detachably coupled to the tube plate, and includes a column which corresponds to the tube of the tube plate. A filter is provided in the column and made of a material which adsorbs or desorbs biochemical materials included in biological samples. A hollow suction port is provided at a predetermined position of the column plate to connect to a vacuum pump. The apparatus is capable of extracting biochemical materials from biological samples by using vacuum pressure without centrifugal separation, thus realizing a simple, convenient and rapid extracting operation, and has a small size so that it rapidly reaches desired vacuum pressure and uniform vacuum pressure can act on the column.
