A system for the purification of DNA and the like comprises a housing having walls (14, 16, 18) forming a reservoir having a chamber (15) for containing a buffer solution, means (32, 40, 42, 48) for circulating a buffer through the reservoir, a disposable cassette (24) within said chamber having first means including a gel (100) for defining a first path extending between an inlet end and an outlet end, a well (88) for introducing a bacterial sample into the path at said inlet end thereof, and a second path intersecting the first path via an elution chamber (26, 116), having a collection chamber (122) including an elution window (128) at said outlet end, and an electrical circuit (52, 56, 58, 60, 62, 64) for selectively applying an electrical potential along each of the paths for selectively moving a plasmid first along the first path from the bacterial well to the elution chamber, then along the second path to the collection window at the end thereof. |
