Abstract: An automated apparatus is programmed to perform a process by arranging a sequence of first icons on a display in the order of the process, wherein the first icons represent functions of the apparatus, and wherein at least one of the first icons provides a visual representation of a function of the apparatus. Said at least one of the first icons can be expanded to show second icons that comprise the function of said at least one of the first icons, and at least one of the second icons provides a visual representation of a subfunction of the apparatus. In a preferred mode, when said at least one of the first icons is expanded, said at least one of the first icons maintains its same sequential relationship on the display to the other of the first icons in the sequence as before it was expanded.

Abstract: A liquid-handling instrument has a worksurface with registration for modular stations to support containers of liquid, pipette apparatus with a pipette tip coupled to a sensing circuit, a robotic translation system for moving the pipette tip, and a control system with an iconic user interface for programming and editing. A gauge block registered on the worksurface provides for calibration using the sensing tip, and register cavities on the worksurface provide for modular stations. There is a wash station fop the pipette tip on the worksurface. An automated laboratory based on the liquid-handling system has heating and cooling and a sealable incubation station as well as a magnetic separation station. Methods are disclosed using the apparatus to convey droplets of liquid, to aspirate with minimum tip contamination, to mix liquids in containers, and to validate the worksurface.
