Abstract
A method and a system are described for mixing liquid chemicals at dynamically changing or static ratios during a given dispense, with extremely high uniformity and repeatability. A mixer includes multiple fluid supply lines including elongate bladders defining a linear flow path and being configured to laterally expand to collect a process fluid and laterally contract to deliver a selected volume of the process fluid to the mixer.
