A system of reagent bottles and naked circuit boards tethered to a laptop lies silent. But at a command, the arrangement whirs into life. Microfluidic pumps transfer culture media from 2-litre bottles into vials filled with bacteria. Other pumps remove waste from the cultures. Beneath each vial, a magnet attached to a computer fan mixes the culture with a stir bar, while other devices control the temperature and optically record the density of the cultures. Meet eVOLVER, an automated system for culturing bacteria or yeast.
