Abstract
Improved self-contained automated assay devices are provided which allow for reliable release of eluent solution upon opening of a pouch with scoring teeth, so that the solution is transferred to a well for carrying out the assay. The improvements comprise using a bibulous member which is moved into the pouch to initiate eluent solution transport or providing for a sudden shock to the solution to initiate flow.
