Title: LARGE SCALE ACOUSTIC SEPARATION DEVICE
Abstract:
Devices (100) for separating a host fluid from a second fluid or particulate are disclosed. The devices include an acoustic chamber (107), a fluid outlet at a top end of the acoustic chamber (114), a concentrate outlet at a bottom end of the acoustic chamber (116), and an inlet (112) on a first side end (122) of the acoustic chamber (107). An ultrasonic transducer (106) on a side wall of the acoustic chamber and reflector at the opposite side wall create a multi-dimensional acoustic standing wave in the acoustic chamber (107) that traps and separates particulates (e.g. cells) from a host fluid. The host fluid is collected via the fluid outlet (114), and the particulates are collected via the concentrate outlet (116). The device is a large-scale device that is able to process liters/hour, and has a large interior volume.
