Abstract

A mixing system includes a flexible mixing bag having an interior surface bounding a compartment, the compartment being adapted to hold a liquid solution. A mixer is disposed within the compartment of the mixing bag. A shaft has a first end and an opposing second end. The first end of the shaft is connected to the mixer within the compartment of the mixing bag. The second end of the shaft is disposed outside of the compartment. A seal is formed between the mixing bag and the shaft or the mixer to enable the shaft to raise and lower the mixer within the compartment of the mixing bag while preventing leaking of the liquid solution.
