This invention relates to a diluting and mixing device which is capable of diluting a first solution to produce a second solution which is mixed with an undiluted third solution, to reproducibly produce a unique series of combined solutions. Each solution in said series of combined solutions may vary only in the concentration of a single (selected) reactant, and typically, each successive solution becomes increasingly more concentrated in the selected reactant. By employing a modification in procedure, each successive solution in said series may become decreasingly less concentrated in the selected reactant. This invention further relates to an automated system comprising the device connected to a stepping motor so as to rapidly and reproducibly produce said series of solutions, said device being further connected to an analyzer means for obtaining chemical, biochemical, or physical chemical data on said series of solutions. This invention especially relates to an embodiment of the device for obtaining kinetic data on enzyme reactions in solutions. The device is useful because it provides a means for rapidly obtaining chemical, biochemical, or physical chemical data on reactions in solution.
