1. An instrument for controlling a chemical reaction of reagents comprising:

  • a microfabricated reagent chamber for containment of a first one of said reagents, said reagent chamber having a first wall and a second wall defining a reagent chamber volume;

    a first Lamb-wave transducer located on said first wall; and

    a second Lamb-wave transducer located on said second wall;

    the reagent chamber volume defined by said first and second walls narrow enough such that when said first and second Lamb-wave transducers are not activated the reagent is substantially contained within said reagent chamber by surface tension, and such that when at least one of said first and second Lamb-wave transducers are activated the reagent is pumped out of said reagent chamber.
