In addition, the device's channels are rhythmically stretched and relaxed at a rate of one heart beat per second by applying cyclic suction to hollow chambers placed on either side of the cell -
lined microchannels to mimic physiological deformations of the glomerular wall.
COS has a far - UV and near - UV channel that use different detectors: two side - by - side 16384 x 1024 pixel Cross-Delay
Line Microchannel Plates (MCPs) for the far - UV, 115 to 205 nm, and a 1024x1024 pixel cesium telluride MAMA for the near - UV, 170 to 320 nm.
