1. A device for preparing tissue comprising: a container; a filter having a peripheral rim portion, wherein the filter is positioned within the container such that the peripheral rim portion engages at least one inner surface of the container and includes side walls that project downward from the peripheral rim to define a first tissue collection chamber and a second filtrate collection chamber; and a flexible membrane, wherein the edges of the flexible membrane are connected to at least one of an inner surface of the container within the peripheral rim and the peripheral rim of the filter to form a fluid-tight seal between at least a part of the at least one inner surface of the device and the first tissue collection chamber, wherein the flexible membrane has sufficient flexibility to allow expansion of the membrane into the first tissue collection chamber to force material contained within the first tissue collection chamber through the filter and into the second filtrate collection chamber upon application of a pressure to the flexible membrane.
