Abstract
A biological sample collection system can include (i) a sample collection vessel having an opening for receiving a biological sample, (ii) a plug assembly that includes a post with a fluid vent therethrough, a collar disposed about the post, and a plug that initially obstructs the fluid vent, and (iii) a sealing cap coupled to the collar and comprising a reagent chamber for storing a sample preservation reagent. The sealing cap is configured to associate and form a fluid tight connection with the sample collection vessel such that associating the sealing cap with the sample collection vessel causes a physical rearrangement of the plug assembly such that the plug is detached from the post, thereby permitting sample preservation reagent to pass from the regent chamber to the sample collection vessel.
