Abstract
Device and method for processing biological, biochemical or chemical samples are provided wherein a first multiwell plate is stacked atop a second multiwell plate. The first multiwell plate has x wells arranged in a regular array, each capable of receiving a separate sample. Each well of the x wells has an outlet at a lower surface of the first plate. The second multiwell plate has y wells arranged in a regular array, each well of the y wells being capable of receiving a separate sample, and wherein y>x. The outlets at the lower surface of the first multiwell plate are arrayed to register with corresponding inlets of a subset of the y wells of the second multiwell plate when the first plate is stacked atop the second plate. A mechanism for aligning the first plate to the second plate is provided, as well as transfer indicia for tracking transfer of sample from the first plate to the second plate. Also, a mechanism for sealing,the first plate to the second plate is provided so that samples can be directly transferred between the first plate and the second plate without cross-contamination occurring in open wells of the second plate.
