Abstract
Disclosed is a dual-stage fluidics system that has reduced pulsation. This system uses inexpensive peristaltic pumps and two reservoirs that dampen pulsations in pressure. Peristaltic pumps are used as air pressure pumps and sheath fluid pumps that are placed between the two pressurized reservoirs and isolate the two reservoirs. Since the two reservoirs are maintained at a substantially even pressure, pulsations are reduced so that the peristaltic pumps essentially provide air flow and sheath fluid flow as needed.
