Figure 1.86 Design of an optimized triangular interdigital micro mixer, termed SuperFocus, and SEM image showing detail of the corresponding feeding zone [20] (by courtesy of AlChE).

The glass version of the SuperFocus mixer is composed of three layers containing similar structures to the standard triangular mixer [M 43] (see above) [20, 37, 39, 121]. Photoetching of a specially glass is used for manufacture.

Figure 1.92 Regular arrangement of liquid lamellae in the focusing chamber of the SuperFocus micro mixer (steel version large arc of interdigital feeds). For better flow visualization, an asymmetric flow ratio (5 1) was chosen, setting the dyed water solution at a lower flow rate [39].

M 44a] [P 41] The liquid mixing time was calculated to 3.5 ms for a SuperFocus mixer creating lamellae about 4 pm thick (see Table 1.6) [39] (see also [121]). This calculation neglects the premixing in the focusing region and the respective residence time.
