Abstract

A method that allows a user to dispense a desired volume of solution from an acoustic dispensing apparatus by allowing the user to select the drop volume to be dispensed. A typical drop volume is in the range of one to twenty-five nanoliters. The method comprises the steps of creating two or more burst curves that give the relationship between liquid level and burst value, using data from the burst curves to create two or more calibration functions, and using data from the calibration functions to create a dispensing data set that is used to set the burst parameter required to dispense the selected drop volume.
