A system for mixing a liquid solution or suspension includes a collapsible container having an interior surface bounding a compartment, the compartment being adapted to hold a liquid solution or suspension. A mixer is enclosed within the compartment of the container. A shaft has a first end connected to the mixer within the compartment of the container and a second end disposed outside of the compartment, the shaft being selectively movable relative to the container. A gas pathway extends from a portion of the shaft disposed outside of the container to a portion of the shaft or mixer disposed within the compartment of the container, the gas pathway extending through at least a portion of the shaft.
