    Abstract: An acoustophoresis device which includes a substantially vertical flow path of the fluid mixture in order to improve separation of particles/secondary fluid from a primary fluid is disclosed. The vertical flow path reduces velocity non-uniformities in the acoustic chamber resulting from gravity forces. The device includes an acoustic chamber in which multidimensional acoustic standing waves are generated. The fluid can be introduced into the acoustic chamber using a dump diffuser in which a plurality of inlets enter near the bottom of the acoustic chamber such that flow symmetry reduces both, gravity driven flow non-uniformities, and any flow interference effects between inlet mixture flow into the acoustic chamber and the continuous gravity driven particle cluster drop out.

    Abstract: Systems and methods for increasing the accuracy of a turbidity sensor are disclosed. The systems include a turbidity sensor and a flow module with a specialized flow path, with the turbidity sensor engaging with the flow module such that a measurement zone of the turbidity sensor is disposed within a flow path of the flow module and a bypass path of the flow module does not pass through the measurement zone. The methods include flowing a fluid containing bubbles into a system that separates the fluid in the flow module into a first stream of fluid containing relatively more bubbles and a second stream of fluid containing relatively fewer bubbles, the first stream flowing through a bypass path that does not pass through the measurement zone, and the second stream flowing through the measurement zone of the turbidity sensor.

    Abstract: Devices for separating a host fluid from a second fluid or particulate are disclosed. The devices include an acoustic chamber, a fluid outlet at a top end of the acoustic chamber, a concentrate outlet at a bottom end of the acoustic chamber, and an inlet on a first side end of the acoustic chamber. An ultrasonic transducer and reflector create a multi-dimensional acoustic standing wave in the acoustic chamber that traps and separates particulates (e.g. cells) from a host fluid. The host fluid is collected via the fluid outlet, and the particulates are collected via the concentrate outlet. The device is a large-scale device that is able to process liters/hour, and has a large interior volume.
