1. A flow cytometer comprising:
a flow cell for transporting particles in a flow stream;
a sheath fluid line for fluidically coupling to a sheath fluid reservoir; and
a fluidic resistance unit positioned between the sheath fluid line and the flow cell, wherein the fluidic resistance unit comprises:
an inlet fluidically coupled to the sheath fluid line;
a valve line fluidically coupled to the inlet, wherein the valve line comprises a series of fluidically coupled valves;
a resistor line fluidically coupled to the inlet, wherein the resistor line comprises a series of fluidically coupled resistors;
a plurality of connectors fluidically coupling the valve line to the resistor line; and
an outlet fluidically coupling the fluidic resistance unit to the flow cell.
