Zusammenfassung:A digital dispense system and method of using a digital dispense system, with unique low-cost pipette-fillable cartridges that provide feedback to a user if fluid chambers of the cartridge do not contain fluid or an incorrect fluid is pipetted into a fluid chamber, are provided. The digital dispense system includes a pipette-fillable fluid cartridge having one or more fluid chambers therein and having an ejection head attached thereto. The ejection head contains fluid ejectors thereon. The fluid ejectors are in fluid flow communication with the one or more fluid chambers of the pipette-fillable fluid cartridge. A fluid detection circuit is disposed on the ejection head and associated with at least one of the fluid ejectors for signaling the presence or absence of fluid in the one or more fluid chambers.
