Abstract
An assay cartridge which has a substantially rectangular base plate, a substantially rectangular top plate, and four side walls. The top plate has a plurality of aligned adjacent reaction wells located on its top side. Each well has a hole at its bottom which opens into a waste reservoir which is the space inside of the base plate, top plate and four walls. A filter membrane is positioned against the underside of the top plate covering the well holes. A port through the base plate allows reducing the pressure in the waste reservoir relative to the pressure over the wells for drawing the liquid phase of a reaction from the well through the filter and into the waste reservoir.
