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.
