Can the flow fluctuations from the FC peristaltic pump be minimized, and about how large are they?
When the pump has been calibrated and flow set either by the speed dials, or from an external voltage, the mean flow will be that desired. However, the pump will produce a pulsating flow. The amplitude and frequency of these pulsations depend on the pump speed, the tube set used in the pump, and possibly on the system perfused by the pump. For example, a FC-TS-015 tube set delivering 100 µl/min may have flow fluctuations of about ±3 µl/min, and half that at 50 µl/min.
