Abstract

Embodiments include assay devices within a single use, disposable cassette for biochemical assays with at least one fluid well and at least one capillary valve. The capillary valve in combination with motion of porous sheets within the assay leads to addition of liquid reagents at different times to the assay although a user adds the liquid reagents to the cassette simultaneously.
