What is claimed is: 1. A buffered dosing device for a material, comprising: a main chamber formed within a body, the main chamber comprising an annular volume sized to hold more than one dose of the material, wherein the body defines an interior passage through an interior of the annular volume of the main chamber; a dosing chamber sized to hold one dose of the material, in fluidic communication with the main chamber; a shuttle comprising an uppermost portion located within the interior passage of the body and a lower portion located within the dosing chamber, wherein the shuttle is adapted for movement between: (i) a first position in which the material can flow between the main chamber and the dosing chamber; (ii) a second position in which the shuttle is depressed and seals the dosing chamber from the main chamber, and permits the material to exit the dosing chamber; (iii) a third position intermediate the first and second positions, in which no material can flow between the main chamber and the dosing chamber, and no material can escape from the dosing chamber; and a locking mechanism that prevents the shuttle from being moved from the first position to the second position until the locking mechanism is released. 2. A dosing device according to claim 1, wherein the locking mechanism comprises locked position in which a spring arm is biased toward the uppermost portion of the shuttle to interfere with movement of the shuttle, and an unlocked position in which the spring arm does not interfere with movement of the shuttle. 3. The dosing device of claim 1, wherein the main chamber is refillable. 4. The dosing device of claim 3, wherein the main chamber may be refilled by removing a cap that forms at least a portion of the main chamber. 5. The dosing device of claim 1, in combination with a carrier tray. 6. The dosing device of claim 1, wherein the device includes a volumetric spacer within the dosing chamber. 7. The dosing device of claim 1, in combination with liquid in at least one of the main chamber and the dosing chamber. 8. A dosing device according to claim 1, wherein the shuttle comprises an activation location that is disposed at an opposite end of the dosing device from a dispensation location where the material exits the dosing device. 9. A dosing device for a material, the dosing device comprising: a body comprising a main chamber and a dosing chamber, wherein the dosing chamber is located in an lower portion of the body, wherein the main chamber comprises an annular volume sized to hold more than one dose of the material, wherein the body defines an interior passage through an interior of the annular volume of the main chamber; wherein the dosing chamber is sized to hold one dose of the material, wherein the dosing chamber is in fluidic communication with the annular volume of the main chamber; a shuttle comprising an uppermost portion located within the interior passage of the body and a lower portion located within the dosing chamber, wherein the shuttle is adapted for movement between: a first position in which the material can flow between the main chamber and the dosing chamber; and a second position in which the shuttle is depressed and seals the dosing chamber from the main chamber, and permits the material to exit the dosing chamber; a sping located within the interior passage of the body, wherein the spring biases the shuttle in the first position; a locking mechanism that prevents the shuttle from being moved from the first position to the second position until the locking mechanism is released. 10. The dosing device of claim 9, wherein the locking mechanism comprises locked position in which a spring arm is biased toward the uppermost portion of the shuttle to interfere with movement of the shuttle, and an unlocked position in which the spring arm does not interfere with movement of the shuttle. 11. The dosing device of claim 9, wherein the shuttle is adapted for movement to a third position intermediate the first and second positions, wherein the material cannot flow between the main chamber and the dosing chamber and the material cannot escape from the dosing chamber when the shuttle is in the third position. 12. The dosing device of claim 9, wherein the main chamber is refillable. 13. The dosing device of claim 9, wherein the main chamber may be refilled by removing a cap that forms at least a portion of the main chamber. 14. The dosing device of claim 9, in combination with a carrier tray. 15. The dosing device of claim 9, wherein the dosing device includes a volumetric spacer within the dosing chamber. 16. The dosing device of claim 9, in combination with liquid in at least one of the main chamber and the dosing chamber. 17. The dosing device of claim 9, wherein the shuttle comprises an activation location that is disposed at an opposite end of the dosing device from a dispensation location where the material exits the dosing device.
