(a) Laminar flow in the H-reactor, observable macroscopically in the tubing (see also Figure 1b) and (b) with low magnification on the chip. Tubings on the left are used as inlets, with a flow rate of about 200 μL/min. The bar is 10 mm. The H-reactor is produced from borosilicate glass, using negative dry film resist and powder blasting, and has a channel width of 150–200 μm and channel depth of 150 μm.
