Abstract

In this study, we present a capillary driven and easily fabricated passive planar baffle micro-mixer with a trigger valve. The micro-mixers were fabricated in PMMA sheets (2 mm in thickness) by CO2 laser ablation and thermal bonding, and the microfluidic experiments were observed and recorded using flow visualization with a CCD. The results show that design of channel height ranges (to 220∼400 μm) can be promoted by modifying the staggered baffle structure, and the meander baffle structure mixer performs the best mixing efficiency (94%) because of longest flow time and shortest average diffusion distance (300 μm) in mixing zone.
