What is claimed is: 1. A rotor assembly, comprising: a rotor; a guide supported by the and having a longitudinal axis; an actuator mounted to the guide and being moveable between a first position and a second position; a resilient member extending axially between the actuator and the guide, the resilient member being configured to bias the actuator to the first position; and an engagement mechanism mounted to the rotor and being moveable relative to the actuator, wherein the engagement mechanism engages a portion of a centrifuge when the actuator is in the first position and disengages from the portion of the centrifuge when the actuator is in the second position. 2. The rotor assembly of claim 1, wherein the portion of the centrifuge comprises a shaft. 3. The rotor assembly of claim 1, wherein the actuator comprises a button that is moveable between the first position and the second position upon application of force thereon of less than approximately 10 pounds. 4. The rotor assembly of claim 1, further comprising a resilient member positioned adjacent to the engagement mechanism and configured to apply a restorative force upon the engagement mechanism that biases the engagement mechanism toward a position wherein the engagement mechanism is engaged with the portion of the centrifuge. 5. The rotor assembly of claim 1, wherein the resilient member comprises a spring. 6. The rotor assembly of claim 1, wherein the engaging mechanism includes a tapered portion positioned adjacent to the actuator when the actuator is in the second position. 7. The rotor assembly of claim 1, further comprising: a sample holder reception region connected to the rotor and configured to receive and hold a sample holder adjacent to the rotor. 8. The rotor assembly of claim 1, wherein the resilient member comprises two springs. 9. The rotor assembly of claim 1, further comprising: a housing that surrounds portions of the actuator, the engagement mechanism, and the resilient member. 10. The rotor assembly of claim 1, wherein the engagement mechanism engages a portion of a centrifugal vacuum concentrator. 11. A method of connecting a rotor assembly to a centrifuge, the rotor assembly having a rotor, a guide supported by the rotor and having a longitudinal axis, an actuator mounted to the guide, a resilient member extending axially between the actuator and the guide, and a latching mechanism mounted to the rotor and being moveable relative to the actuator, the method comprising: placing the rotor assembly adjacent to a portion of a centrifuge; latching the rotor assembly to the portion of the centrifuge using the latching mechanism mounted to the rotor assembly; and unlatching the rotor assembly using the actuator mounted to the rotor assembly. 12. The method of claim 11, further comprising: preventing unlatching of the rotor assembly from the portion of the centrifuge by biasing the latching mechanism in a latched position. 13. The method of claim 11, further comprising: encasing a portion of the latch assembly within a housing. 14. The method of claim 11, further comprising: applying force to the actuator to unlatch the rotor assembly from the centrifuge. 15. The method of claim 14, further comprising: biasing the actuator with a resilient member that at least partially counteracts the force applied to the actuator when unlatching the rotor assembly from the centrifuge. 16. The method of claim 14, wherein the applying force step comprises pressing on a button to unlatch the rotor assembly from the centrifuge. 17. A rotor assembly, comprising: a centrifuge rotor; a guide supported by the rotor and having a longitudinal axis; a button mounted to the guide and moveable between a first position and a second position; a resilient member extending axially between the button and the guide, the resilient member being configured to bias the button to the first position; a locking mechanism mounted to the rotor and being positioned adjacent to the button; and a tab protruding from the locking mechanism and configured to engage a portion of a centrifuge when the button is in the first position.
