Fig. 5: Application of a bubble removal device in a concentration gradient generator.
From: A bioinspired bubble removal method in microchannels based on angiosperm xylem embolism repair
a SEM image of bubble trappers in the channel. b The bubble removal device could be capable of eliminating bubbles before blue ink flowed into the concentration gradient generator. c Both ink and fluorescein flow through the bubble removal device before the concentration gradient generator. The plot indicates the theoretical and experimental concentrations of fluorescence in the collecting reservoir. The micrographs show the fluorescence intensity with respect to the concentration
