Abstract
A clarification system and method of using for plasmid DNA that is centrifugation-free. The system is comprised of a coarse filter, about 50 to about 200 microns pore size, followed by a prefilter of about 1 to about 2 micron pore size and then a final filter of about 0.22 micron. Preferably, the prefilter and final filter are combined into one filter housing to reduce system hold up volume and enhance recovery of the plasmid DNA. The method allows for continuous as well as batch operation.
