Figure 1.
Automated plaque picker. Plaque dishes are stacked in the carousel (left), picked up by an XY lead screw stage (bottom), imaged over the lighting/imaging station (center), and picked by the main needle turret (center). Plaques are picked into plates retrieved from a carousel of cassettes (right). The instrument is shown here picking plaques from a dish and placing into a microtiter plate held by the server arm. The sterilization coil and wash stations are just visible below and behind the needle turret.
