Abstract: An apparatus includes a microfluidic passage, a chamber, an inlet connecting the microfluidic passage to the chamber, a sensor proximate the inlet to sense fluid within the inlet, a first nozzle, a first fluid driver to move fluid through the first nozzle to draw fluid across the inlet, a second nozzle, a second fluid driver to move fluid through the second nozzle to draw fluid across the inlet and a controller. The controller sequentially actuates the first fluid driver and the second fluid driver.
