Patent ID: 7383967

Claim:
A method for depositing fluids, comprising: depositing fluid substantially free of air bubbles from a pump, wherein depositing fluid substantially free of air bubbles comprises moving fluid through a substantially vertically aligned fluid path provided by a multistage pump having a upwardly oriented first pumping means and a upwardly oriented second pumping means in fluid communication provided via the fluid path with the first pumping means, wherein the first pumping means is operable to pump the fluid through the fluid path to the second pumping means and the second pumping means is operable to collect or dispense the fluid through an outlet coupled to the second pumping means via the fluid path, wherein the second pumping means is operable to collect or dispense the fluid at a rate of operation independent from a rate of operation of the first pumping means and the fluid path is substantially consistently upward throughout the multistage pump as the fluid flows through the first pumping means and the second pumping means.
