ABSTRACT:
A process for the purification of DNA and the like comprises a housing having walls forming a reservoir having a chamber for containing a buffer solution, means for circulating a buffer through the reservoir, a disposable cassette within said chamber having first means including a gel for defining a first path extending between an inlet end and an outlet end, a well 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, having a collection chamber including an elution window at said outlet end, and an electrical circuit 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.
