ABSTRACT:
An apparatus for the purification of DNA and the like comprises a housing having walls forming a reservoir having a plurality of chambers for containing a buffer solution means for circulating a buffer through the reservoir, a disposable cassette within said housing having first means including a gel for defining a first path extending between a first pair of the chambers, a well for introducing a bacterial sample into the path at one end thereof, and a second path intersecting the first path via an elution window at one end, having a collection window at the other end and extending between a second pair of the chambers, 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 window, then along the second path to the collection window at the end thereof.
