Abstract
A biological sample collection system can include a sample collection vessel having a closed first end and an open second for receiving a biological sample. The system can additionally include a sealing cap configured to associate with the sample collection vessel, a reagent chamber secured within an interior space of the sealing cap and retaining a measure of sample preservation solution, a shim circumferentially associated with a proximal end of the reagent chamber and spanning the distance between the reagent chamber and the interior sidewall of the sealing cap, and a plug having a diaphragm configured to selectively engage the shim and form a seal for retaining the sample preservation solution within the reagent chamber. Associating the sealing cap with the sample collection vessel displaces the diaphragm from the shim and breaks the seal formed therebetween, opening a fluid path between the reagent chamber and the sample collection chamber.
