Abstract: A reactor (1) for performing biochemical processes, particularly for extraction, purification, enrichment, sedimentation, comprising a container which is provided with at least one mouth (2) which is associated with closure means (3) of the removable type, the container having internally at least one process compartment (4), adapted to accommodate a sample of biochemical material to be processed, at least one containment chamber (5) for a process agent, and at least first means for transferring the process agent from the containment chamber to the process compartment.

Abstract: A process is disclosed for extracting genomic DNA from a biological sample containing a cell source comprising lysing the biological sample with a first cationic detergent in a solution of high salt concentration greater than 0.5M, under heating at 40.degree. to 80.degree. C., so as to solubilize nucleic acids and proteins present in the cell source. The lysed solution is then extracted with an organic solvent by leaving the DNA in the aqueous phase and precipitating any protein present in the aqueous phase. The DNA is then precipitated from the aqueous solution by diluting it at a salt concentration of below 0.5M and adding thereto a second cationic detergent.
