Patent ID: 8641987

Claim:
A sample chamber array, comprising: a first member affixed to a second member, wherein the first member and second member comprise a flexible material; a first concave-shaped portion of the first member mated with an invertible second concave-shaped portion of the second member, wherein the first and second concave-shaped portions are configured to be biased to engage each other with sufficient force to prevent the passage of fluid between the concave-shaped portions, and wherein the first and second concave-shaped portions are further configured to form a sample chamber when the second concave-shaped portion is moved from a concave shape to a convex shape; and at least one reservoir in fluid communication with the sample chamber when the second concave-shaped portion is moved to the convex shape, wherein said at least one reservoir is fillable with a liquid biological sample, wherein the formation of the sample chamber between the first and second concave-shaped portions causes a pressure drop between the at least one reservoir and the formed sample chamber thereby transporting said biological sample into said formed sample chamber from said at least one reservoir and a device configured to apply an external suction, at a predetermined force, to an outside surface of the invertible second concave-shaped portion of the second member to invert the invertible second concave-shaped portion of the second member.
