High-throughput isolation of ultra-pure plasmid DNA by a robotic system -- BMC Biotech - "Here we describe a custom-made, automated device, which uses a special protocol to isolate plasmid DNAs with a purity sufficient for transfections into mammalian cells. Approximately 1,600 ultra pure plasmids can be isolated in a 96-well plate format within 12 hours. As a unique feature the robot comprises the integration of a centrifuge instead of expensive columns, the use of a custom-made pipetting head with a movable gripper, especially designed shaking platforms and an acetone wash facility."
