1. A fluid system for a sample processor, the fluid system comprising:
a flow cell unit comprising a sample port, a processing fluid port, and a vacuum port;
a sample container;
a sheath fluid container;
a sample line configured to communicate a sample from the sample container to the sample port of the flow cell unit;
a processing fluid line configured to communicate a sheath fluid from the sheath fluid container to the processing fluid port of the flow cell unit, wherein the processing fluid port of the flow cell unit is configured to connect to the processing fluid line and receive the sheath fluid from the sheath fluid container;
a vacuum line in communication with the flow cell unit; and
an air pump comprising a first output port and a second output port, wherein pressurized gas is generated by the air pump at the first output port, the first output port is in communication with the sample container and the sheath fluid container, a vacuum is generated by the air pump at the second output port, and the second output port is in communication with the vacuum port of the flow cell unit through the vacuum line, wherein the air pump includes a vacuum source and a pressure source.
