Abstract: A method of making a test device comprised of a container divided into two chambers, each holding a volume of a clear test liquid, the chambers separated by a porous barrier. The liquid is introduced into the lower chamber by adding a liquid to the upper chamber through the open top of the container and then applying a vacuum to completely evacuate air from the lower chamber by drawing the air through the barrier and liquid in the upper chamber.
