Abstract
An apparatus for measuring a volume of fluid includes at least one emitter configured to project a signal toward a predetermined position of a sample container, at least one receiver configured to receive the signal after the signal interacts with the sample container and a fluid transfer device in communication with the receiver and sample container. A change in the signal received by the receiver indicates when the fluid has dropped below the predetermined position. The apparatus determines a volume of fluid that the fluid transfer device has removed from the sample container when the receiver detects that the fluid has dropped below the predetermined position.
