Hello,
My microfluidic device has three inlets, one for inner phase, one for middle phase, and another for outer phase. I found that the flow rate of inner phase was not correct in the channel. I set the flow rate of inner phase to be 10 uL/hr, but the actual flow of the phase was much faster. And when I pulled the tubing for inner phase out of the device, I saw that the flow rate must be at the magnetiude of 1000 uL/hr. But a few seconds after taking out the tubing, the flow rate of inner phase dropped significantly.
I assume it is because of the flow resistance within the channel. Is there a possible way to solve this problem? Thank you very much!
This is not a question of general discussion rather a more practical thing. If your flows are not correct, sure there will be something wrong. Just ask for help from your colleagues or some one who is experienced with your microfluidics platform.
