Characteristics, tricks and tips
Transient pressure drop when opening the valve
When opening the outlet valve, the pressure measured by the sensor briefly (~1 sec) decreases and before stabilizing at its initial value. This comes from the fact that, before opening the valve, the sensor measures the pressure inside the pressure source and, at the opening of the valve, it measures a mean between pressure inside the generator and inside the microfluidic device connected to the outlet. The measured pressure quickly comes back to its initial value when the pressure on the microfluidic device becomes equal to the pressure in the pressure source. To reduce this time-lapse, one can reduce the dead volume between the pressure source and the microfluidic device.
Small permanent pressure shift when opening the valve
When opening the valve for the first time after setting the pressure with the tuning button, the displayed pressure permanently shifts by one or two mbar. This comes from the fact that the membrane of the internal pressure regulator changes position with the first opening of the outlet. This phenomenon does not occur for further valve switches.
Pressure source warm up
During the first 15 minutes of utilization, the pressure of the generator could change due to the components warm up. To get optimal performance, we recommend turning on the pressure sourcer at least 15 minutes before the beginning of your microfluidic experiment.
Friction of the pressure tuning button
The pressure source tuning button is directly linked to the spring of the internal regulator. The spring of the pressure source  is compressed when increasing the pressure. The compression of the spring leads to a sensation of friction when turning the knob at the top of the pressure range.
