Patent ID: 8602958

Claim:
A method of collecting liquid from a microtiter plate, the method comprising: providing a microtiter plate having a top planar surface and a plurality of material retention regions containing liquid, each material retention region of the plurality of material retention regions having an open end proximal to the top planar surface and a closed end opposite the open end, wherein the microtiter plate contains a total volume of liquid split between the plurality of material retention regions and applied through the open end of the each material retention region of the plurality of material retention regions, each of the plurality of material retention regions containing an individual, discrete volume of liquid, and each individual, discrete volume of liquid being less than the total volume; coupling a receptacle having a perimetric wall, which defines an opening, and an empty volume equal to or greater than the total volume of the microtiter plate with the opening facing the top planar surface of the microtiter plate; and centrifuging liquid from the microtiter plate to the receptacle, such that the individual, discrete volumes of liquid from the plurality of material retention regions pass through the open ends of the plurality of material retention regions and through the opening and collect in the receptacle as one continuous volume of liquid.
