A pressure gauge may be coupled to a supply line which carries liquid from a bottle to either one or more mixing vessels and/or one or more reactors in a combinatorial processing tool. A control device may monitor the pressure measured by the pressure gauge, and the control device may be configured to change the pressure supplied to the bottle based on a comparison of the measured pressure to a pre-determined pressure value. The control device may adjust the pressure provided to the bottle using a pressure regulator coupled to the pressure source. By changing the pressure provided to the bottle, the control device may maintain a relatively constant flow rate of fluids from the liquid source into one or more mixing vessels and/or the one or more reactors.
