Abstract: A sample collection system can include a sample collection vessel having a sample collection chamber with an opening configured to receive a sample into the sample collection chamber. The sample collection system can additionally include a selectively movable sleeve valve configured to associate with the opening of the sample collection chamber. The sample collection system can include a sealing cap that is configured to associate with the selectively movable sleeve valve and with the sample collection vessel. The sealing cap can include a reagent chamber having reagent(s) stored therein, and when the sealing cap is associated with the sample collection vessel, the selectively movable sleeve valve opens, dispensing the reagent(s) into the sample collection chamber. When the selectively moveable sleeve associates with the sample collection chamber, an outer sleeve slides relative to an inner vessel, opening the sleeve and dispensing reagent into the sample collection chamber.

Abstract: A biological sample collection system includes (i) a sample collection vessel having an opening for receiving a biological sample, (ii) a selectively movable valve comprising a core and a collar disposed about the core, and (iii) a sealing cap coupled to the collar and including a reagent chamber for storing a measure of sample preservation reagent. The sealing cap is configured to associate and form a fluid tight connection with the sample collection vessel. Associating the sealing cap with the sample collection vessel causes a physical rearrangement of the core relative to the collar such that a fluid vent associated with the core is placed into fluid communication with the reagent chamber, thereby permitting sample preservation reagent to pass from the regent chamber to the sample collection vessel.

Abstract: A biological sample collection system includes (i) a sample collection vessel having an opening for receiving a biological sample, (ii) a selectively movable valve comprising a core and a collar disposed about the core, and (iii) a sealing cap coupled to the valve and including a reagent chamber for storing a sample preservation reagent. The valve is configured to retain the sample preservation reagent in the reagent chamber when the valve is in a closed configuration. The sealing cap is configured to associate and form a fluid tight connection with the sample collection vessel. Associating the sealing cap with the sample collection vessel causes the valve to be placed in an open configuration in which a fluid vent through the core is placed into fluid communication with the reagent chamber, thereby causing or allowing sample preservation reagent to pass from the regent chamber to the sample collection vessel.

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.

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.

Abstract: A biological sample collection device (e.g., swab) can include elongated body (e.g., shaft) extending from a collecting portion (e.g., swab body or tip) at a first end to a connecting portion at a second end along a longitudinal axis.
