The aim of this work was the design, manufacturing and testing of a small, low cost setup useful for research on microfluidics and teaching as well. The setup was designed to be modular and was assembled using only of-the-shell parts and pieces. The final device is composed of a base, where all parts and pieces are assembled, accessories to provide continuous flow of gas (air) or liquid (water) fluids and two optical digital microscopes for diagnosis of fluid condition. The corresponding photos and videos are directly collected on a computer. The setup performs contact angle measurements even on rough surfaces and using small drops, up to 10 µL, and showed to be appropriate for microfluidic analysis of the mesostructures, such as microchannels with 100 µm on diameter.
