Abstract
A reagent dispensing apparatus is provided including a positive displacement syringe pump in series with an air brush dispenser. The pump is controlled by a stepper motor or the like to provide incremental or continuous flow of reagent to the air brush dispenser. The air brush dispenser mixes the predetermined incremental quantity or continuous flow of reagent with pressurized air to atomize the reagent and produce an aerosol spray pattern which coats the substrate.
