Abstract
A micromachined, high Reynolds number, sub-millisecond liquid mixer for the study of chemical reaction kinetics. This bulk micromachined silicon mixer is capable of initiating and quenching chemical reactions in intervals as short as 100 .mu.s. The mixer chip contains two tee mixers connected by one channel which serves as a reaction chamber. Each tee mixer consists of opposing channels where liquids meet head-on and exit into a third channel forming the base of a 'T'.
