1. A device for collecting and stabilizing a biological sample, the device comprising:

  • (a) a housing comprising an open end portion, a closed end portion, and an interior space;

    (b) a retainer insertable into the interior space of the housing, the retainer comprising a vessel for receiving a solution and a penetrable seal for enclosing the solution within the vessel;

    (c) a collector removably engagable with the open end portion of the housing and capable of sealingly closing the open end portion of the housing, the collector comprising an absorbent member for collecting the biological sample,wherein, when the collector is engaged with the open end portion of the housing, the absorbent member is received in the housing and the collector breaks the penetrable seal of the retainer that has been inserted into the interior space of the housing and propels the solution to flow through the absorbent member, thereby releasing the biological sample from the absorbent member and facilitating mixing of the biological sample with the solution; and

    wherein the vessel has an open top, and a closed bottom, the closed bottom is formed with a central portion recessed inwardly toward the open top of the vessel or a protrusion protruded inwardly toward the open top of the vessel to compress the absorbent member when the collector is engaging or engaged with the open end portion of the housing, thereby squeezing the biological sample out of the absorbent member.
