a container body defining an internal chamber configured to receive a sample, wherein the container body defines a first distal container end, a collection region at least a portion of which defines a collection diameter, and a pellet region at least a portion of which defines a pellet diameter, wherein the collection diameter is greater than the pellet diameter, and wherein the pellet region is defined between the first distal end and the collection region in the internal chamber;
a plunger configured to be disposed at least partially within the internal chamber, the plunger comprising:
a longitudinal member defining a first distal end, a second distal end, and an axis extending between the first distal end and the second distal end; and
a plunger seal positioned about the longitudinal member at a location between the first distal end of the longitudinal member and the second distal end of the longitudinal member, the plunger seal defining a plunger seal diameter perpendicular to the axis,
wherein the plunger seal diameter is greater than or equal to the pellet diameter and less than the collection diameter,
wherein at least a portion of the longitudinal member between the location and the first distal end of the longitudinal member defines a plunger diameter that is less than the plunger seal diameter, and
