Claim:
1. A method of delivering a solution flow, comprising: causing a reagent and a primer to flow into a first mixing channel; stopping the reagent and the primer in the first mixing channel by keeping both ends of the first mixing channel at the same pressure for at least a threshold amount of time so as to allow the reagent and the primer to mix, thereby forming a reagent/primer mixture; causing a buffer to flow into a second mixing channel, the first and second mixing channels being located on a mixing chip, wherein the mixing chip is separate and in fluid communication with a PCR chip through an interface chip, wherein the PCR chip is configured for performing an amplification reaction; after holding the reagent and the primer in the first mixing channel for at least the threshold amount of time, drawing, from the first mixing channel, the reagent/primer mixture into a common exit channel located on the mixing chip; and adding DNA samples to the reagent/primer mixture while the reagent/primer mixture is in the interface chip.
