1. An apparatus comprising:
a base;
a pair of walls that extend upwardly from the base, wherein the pair of walls are elongate along a first axis, wherein the pair of walls are parallel or generally parallel to each other, wherein each wall of the pair of walls defines an upper end, an inner surface, and an outer surface;
a plurality of transverse members having a respective first end and second end that are spaced along a second axis that is perpendicular to the first axis, wherein each transverse member of the plurality of transverse members comprises:
a top surface;
a bottom surface that is spaced from the top surface along a vertical axis that is perpendicular to each of the first axis and the second axis;
a respective first downwardly extending projection and second downwardly extending projection at each end of the first end and the second end, wherein the respective first downwardly extending projection and second downwardly extending projection are spaced from each other along the second axis, wherein the upper end of a respective wall of the pair of walls is received between the respective first downwardly extending projection and second downwardly extending projection; and
at least one cross member to support sample media, which extends between at least two of the transverse members along the first axis and rests upon the at least two of the transverse members.
