A system and method for dispensing a sample using a self-dispensing system ( 1) including a sample storage device (2), a dispensing mechanism (3), and a driving mechanism (4) for driving the dispensing mechanism. The dispensing mechanism is formed as part of and is in dispensing communication with the sample storage device. Preferably the dispensing mechanism is a positive displacement mechanism and includes an inlet valve, an actuator, and an outl et valve. The driving mechanism may be positioned internal or external to the dispensing mechanism and drives the dispensing mechanism thereby inducing a flow of a measured quantity of sample (6) into or out of the storage device. Preferably, the dispensing mechanism is relatively inexpensive and is disposable. The system and method alternatively, may include a plurality of storage devices each having a corresponding dispensing mechanism arranged in , for example, a plate (21). The system and method provide for precision and reproducible dispensing of a sample with improved efficiency. |
