Abstract
A reservoir for use in testing a liquid as part of a microfluidic testing system, includes a testing chamber configured to receive the liquid to be tested. A liquid inlet is fluidly coupled to the testing chamber to allow ingress of the liquid into the testing chamber. A gas outlet is fluidly coupled to the testing chamber to allow egress of gas out of the testing chamber. The gas outlet has an elevation that is higher than an elevation of the liquid inlet such that, as the testing chamber is rotated, the gas is expelled out of the testing chamber through the gas outlet, thereby reducing or preventing a presence of gas bubbles in the liquid.
