摘要：
Devices for separating materials from a host fluid are disclosed. The devices 100 include a flow chamber, an ultrasonic transducer 120, and a reflector 130. The ultrasonic transducer 120 and reflector 130 create an angled acoustic standing wave oriented at an angle A relative to the direction of mean flow 116 through the flow chamber. The angled acoustic standing wave 122 results in an acoustic radiation force having an axial force component that deflects the materials, so that the materials and the host fluid can thus be separated. The angled acoustic standing wave can be oriented at an angle of about 20° to about 70° relative to the direction of mean flow through the flow chamber to deflect, collect, differentiate, or fractionate the materials from the fluid flowing through the device at flow rates of about 400 mL/min up to about 700 mL/min.
