  • Patent number: 9457329
    Abstract: The invention relates to a system and method for mixing two or more solutions. Provided is an integrated system for generating a homogeneous solution from two or more input solutions, comprising: a mixer chamber containing a magnetic stir bar; a means for rotating the magnetic stir bar; and an user interface for input a chosen flow rate. The mixer chamber comprises a mixer chamber body including a movable upper part which defines a mixer chamber volume; one or more solution inlets; an solution outlet; the magnetic stir bar; and a means for adjusting the mixer chamber volume. In response to the input flow rate, the mixing chamber volume is adjusted to an optimal volume, by the movement of the movable upper part, controlled by the means for adjusting the mixer chamber volume. Also provided are methods of using the system to achieve homogeneous mixing of two or more solutions.
