1. A device for washing a composition comprising red blood cells, the device comprising:
- a body having a first surface, a second opposing surface, a first side, a second opposing side, a first end, and a second end, the body defining a channel extending along a longitudinal axis from the first end to the second end, wherein the channel comprises a separation region and a mixing region, the body further including a first planar shelf proximate the first end and arranged to isolate a first inflow stream from a second inflow stream prior to the first inflow stream and the second inflow stream entering the mixing region;
a first sidewall located along the first side within the channel and extending along the longitudinal axis;
a first protrusion extending from the first surface and adjacent to the first sidewall, the first protrusion extending a length of the first sidewall;
a second sidewall located along the second side within the channel and extending along the longitudinal axis, the first sidewall and the second sidewall being a phantom material;
a second protrusion extending from the first surface and adjacent to the second sidewall, the second protrusion extending a length of the second sidewall;
a first wave component coupled to the first surface; and
a second wave component coupled to the second surface,wherein the separation region of the channel is positioned between the first wave component and the second wave component, and wherein the first wave component and second wave component are configured to generate a first standing acoustic wave.

Abstract
Devices for washing a composition including cells are provided. The devices include a separation channel, a first wave component and a second wave component. The separation channel is positioned between the first and second wave components. Collectively, the wave components generate a standing bulk acoustic wave that isolates cells from the composition.
