Abstract: A method for performing chemically analyzing samples (e.g. bodily fluids) dispensed with an acoustic ejection device is disclosed. A method preparing a sample for analysis by centrifuging the sample in a sample collection device in fluid communication with an acoustic ejection device is disclosed. A method for laboratory analysis of biological and/or other fluids, wherein a single electromechanical pump including an acoustic ejection device draws and ejects fluids is disclosed. A device for dispensing a fluid, where a ratio between a reservoir of the device and an ejection chamber is between 50 and 4,000 is disclosed. A system including a plurality of acoustic ejection devices in an environmentally enclosed housing is disclosed.
