Figure 7

Single-channel polydispersities and pooled polydispersity over the 4- and the 8-channel device. Individual channels of each scale-up device generate dual-layer microbubbles with respective mean polydispersity indexes of 2.5% and 2.3%, quite monodisperse and well below respective overall pooled polydispersity indexes of 6.9% and 8.0%.
