Abstract: A removable cartridge is configured to receive one or more fluid sample for analysis. The cartridge includes multiple sample wells. Each of the sample wells includes a sensor with a first electrode, a second electrode, and a third electrode. The electrodes are arranged to contact the sample fluid. A base is configured to receive the cartridge. The base is configured to send and receive signals to the cartridge when the cartridge is received by the base. A controller is configured to exchange signals with the first electrode, the second electrode, and the third electrode. The controller configured to identify each sample well of the cartridge. The controller is configured to determine a status of each sample well of the cartridge. The controller is configured to perform an analysis of a substance within at least one of the sample wells.

Abstract: A heat exchanger that includes a first manifold; a second manifold; a plurality of refrigerant tubes configured to fluidically couple the first and second manifolds; a plurality of fins placed between the plurality of refrigerant tubes, such that the fins and refrigerant tubes define a core having a plurality of open channels that allow air to flow there through; and a water-shedding device positioned approximate to the first manifold with a separation distance being maintained there between. At least a portion of the water-shedding device extends into one or more fin free windows located between the plurality of refrigerant tubes, such that condensate is extracted from between the refrigerant tubes.
