LIQUID FLOW AND CONTROL IN A BIOLOGICAL TEST ARRAY

摘要

A microbiological test array (12) with a generally flat base (11) having a plurality of upwardly projecting microwells (44) connected by a microchannel (42) to an open reservoir (50) formed in a top surface (13) generally parall el to the base (11) of the test array (12). The reservoir (50) has an opening t o permit an inoculum-broth liquid solution to flow from the reservoir through the microchannel (51), to a sacrificial evaporation well (46) having an air vent port (48) adapted to control a vacuum filling process, and subsequently to be distributed into each of the plurality of microwells (44).
