1. A system for evaluating a volume of a liquid, the system comprising:
a device comprising a channel for holding the volume of liquid, the device comprising:
an upper plate;
a lower plate, wherein the lower plate includes an extension region that extends beyond a proximal end of the upper plate;
means for maintaining a separation distance between the lower plate and the upper plate, wherein an internal facing surface of the lower plate and an internal facing surface of the upper plate form opposing sides of a channel having an entrance at the proximal end of the upper plate, wherein the extension region includes a deposition region that is located beyond the proximal end of the upper plate and borders the entrance for the channel; and
a repellant barrier at least partially defining an extent of the deposition region in the extension region, wherein the repellant barrier has a height or depth less than the separation distance at the entrance for the channel.
