Abstract

A fluidic testing method is presented that includes flowing an initial amount of liquid down a first inlet channel of a single-port fluidic testing system, and splitting the initial amount of liquid from the first inlet channel into a plurality of second inlet channels. Each second inlet channel is coupled to a given test chamber of a plurality of test chambers, wherein each of the plurality of test chambers has a wall that defines a longest side of a given test chamber, and wherein each of the plurality of test chambers has only one opening through the wall of a corresponding test chamber. The method also includes filling each of the plurality of test chambers with a final amount of liquid, the final amount being substantially equal in each of the test chambers and summing from each test chamber to equal the initial amount of liquid.

Dependent claims

A method comprising:

flowing an initial amount of liquid down a first inlet channel of a single-port fluidic testing system;
splitting the initial amount of liquid from the first inlet channel into a plurality of second inlet channels, each second inlet channel coupled to its own corresponding test chamber of a plurality of test chambers via an opening through a wall of the corresponding test chamber, wherein the wall defines a longest side of the corresponding test chamber, and wherein the opening is the only opening into the corresponding test chamber;
filling each of the plurality of test chambers with liquid;
and
drawing the liquid away from each of the plurality of test chambers through the opening of each corresponding test chamber, wherein the drawing leaves behind a predetermined amount of the liquid below a height at which the opening is disposed along the wall of each corresponding test chamber.
