Digital Dispense System

A method for staining slides without dipping or immersing slides in a dye, comprising:

• providing a digital fluid droplet ejection system housed in a compact housing unit, the fluid droplet ejection system including:
• a fluid droplet ejection head and fluid cartridge containing one or more fluids to be dispensed,
• a cartridge translation device for moving the fluid droplet ejection head and fluid cartridge back and forth over a slide holder in an x direction, and
• a slide holder translation device for moving one or more slides back and forth beneath the fluid droplet ejection head and fluid cartridge in a y direction orthogonal to the x direction;
• attaching a digital display device to the digital fluid droplet ejection system;
• ejecting fluid from the fluid droplet ejection head and fluid cartridge in one or more locations on the slide while moving the fluid cartridge in the x direction and moving the one or more slides in the y direction;
• and
• displaying fluid volume information to a user on the digital display device, wherein the fluid volume information is selected from the group consisting of relative fluid volume, absolute fluid volume, and a combination of relative and absolute fluid volumes.

A method for dispensing fluid into wells of a micro-well plate, the method comprising:

• providing a digital fluid droplet ejection system housed in a compact housing unit, the fluid droplet ejection system including:
• a fluid droplet ejection head and fluid cartridge containing one or more fluids to be dispensed,
• a cartridge translation device for moving the fluid droplet ejection head and fluid cartridge back and forth over a micro-well plate holder in an x direction, and
• a micro-well plate holder translation device for moving a micro-well plate back and forth beneath the fluid droplet ejection head and fluid cartridge in a y direction orthogonal to the x direction;
• attaching a digital display device to the digital fluid droplet ejection system;
• ejecting fluid from the fluid droplet ejection head and fluid cartridge into one or more wells of the micro-well plate while moving the fluid cartridge in the x direction and moving the micro-well plate in the y direction;
• and
• displaying fluid volume information to a user on the digital display device, wherein the fluid volume information is selected from the group consisting of relative fluid volume, absolute fluid volume, and a combination of relative and absolute fluid volumes.
