RoboDesign International of Carlsbad, Calif., has received US Patent No. 6,979,425, "High capacity microarray dispensing." The patent claims a microarrayer for spotting solution onto slides in an automated microarray dispensing device. A method is also described for automatically moving microplates to a solution removal area, where a dispense head accesses each microplate at the solution removal area to remove solution from the microplate. The dispense head then moves to a slide positioning station to spot slides at the slide positioning station.
