Vista software completely automates the set-up and operation of the and liquid handling automation systems. Researchers and technicians can easily run archived applications or create new applications with a minimum of effort or training. This application-focused software uses a Graphical User Interface that employs ordinary commands such as "Select" and "Drag-and-Drop". First time users are amazed at how little time it takes to set up and run an application.

Running an Application from the User's Archives The user opens the Application Browser with the mouse and selects the appropriate application. A pictorial representation of a numbered and "gridded" work deck, known as the Universal Device Platform (UDP), appears on the screen. The user follows this pictorial guide to position reagent containers, rinse stations, microplates, disposable tip racks, and all other devices on the Universal Device Platform. The user then simply selects "Run" to start the application. To change applications, the user chooses another application from the Application Browser and proceeds as above.

Setting up a New Application The user sets up a new application on an or liquid handling automation system in just five steps..

1. Select the peripherals needed in the application from the user's inventory of pumps, rinse stations, probes, and other devices.

2. Select the types of sample formats and containers: 96, 384, and 1536 microwell plates, test tube racks, vial racks, beaker racks, etc.

3. Move plates, racks, and rinse stations with the "Drag and Drop" command onto a "snap-to-grid" image of the Universal Device Platform. Vista software manages the dimensions and tolerances associated with these placements.

4. Put together the sequence and timing of robotic movements and the control commands for the pumps and other devices required in the application. This is done by first selecting a microwell, test tube, rinse station, or other device location, clicking on a peripheral such as a pump, and then setting the peripheral's operating parameters such as dispensed or aspirated volume, rate of dispensing or aspiration, etc. A record of robotic movements and device tasks is automatically stored and displayed in the Activity List section of the screen.

5. Name the application and archive it in the Application Browser. The physical layout on the Universal Device Platform as well as the sequence and timing of all robotic steps are stored with the application.
