ABSTRACT:
The fluidic system of the preferred embodiment includes a sheath pump to pump sheath fluid from a sheath container into an interrogation zone, a sheath volume measurement device to measure the fluid in the sheath container, a waste pump to pump the sheath fluid and a sample fluid as waste fluid from the interrogation zone into a waste container, and a waste volume measurement device to measure the fluid in the waste container. The system also includes a controller connected to the sheath pump, the waste pump, and the volume measurement devices. The sheath pump and/or the waste pump draw sample fluid from a sample container into the interrogation zone, which functions to provide a location for the fluidic system and an optical system of the flow cytometer to cooperatively facilitate the analysis of the sample fluid.
