Hi Anpan,
Their source will probably be one we don't think of but from my experience,
they come from: dissolved gas in the liquid (degass the liquid before),
small gas quantities captured in the connectors or between them or gas
adsorbed to system walls (pre-wet the system), cavitation in the liquid
(avoid quick suction or pumping and valve actuation)
Good luck
Shay

bubblesinthemicrofluidicdevice)

Dear all

Back to the annoying bubbles. We try everything to get rid of them, but
does anyone have an idea how they formed. Maybe then we could find
better ways to eliminate them. A reference on this issue will be great!

All the best

Anpan
