ABSTRACT:
A reaction vessel, test device, and method of detection or measurement are disclosed, featuring the use of at least two operatively connected zones formed by transport surfaces spaced apart throughout most of the zones a capillary distance. The zones are fluidly connected by meniscus control means effective to stop capillary flow of the liquid from one zone to the other, until an externally generated actuation pressure is applied.
