Line chart showing flowrate in microliters-per-minute over time in seconds when the MV-2 is opening. A teal line shows the data for 200 millibar fluid pressure, showing the flowrate rocket to above 1500 microliters-per-minute when the valve is opened and quickly settling to a steady 690 microliters-per-minute. A yellow line shows the data for 100 millibar fluid pressure, showing the flowrate rocker to above 500 microliters-per-minute when the valve is opened and quickly settling to a steady 345 microliters-per-minute. 0.00 0.25 0.50 0.75 Time (s) 0 500 1,000 1,500 2,000 Flowrate (μL/min)
