Centrifugal micro -fluidic chip

The utility model relates to a centrifugal micro -fluidic chip, including at least one micro -fluidic unit, this micro -fluidic unit includes the application of sample pond, divides appearance component and reaction component. Divide the appearance component to include arc -shaped passageway and a plurality of branch appearance buffer pool, a plurality of branch appearance buffer pools are followed arc -shaped passageway's periphery is seted up, and divides radial outside extend of appearance buffer pool along arc -shaped passageway, divides the volume of appearance buffer pool to equal, and divides the degree of depth of appearance buffer pool to reduce in proper order from arc -shaped passageway's entrance point to exit end direction. Above -mentioned centrifugal micro -fluidic chip application of sample volume is controlled easily, gets into treating that the tracer liquid is long -pending and equal that can detect multiple pathogenic organism simultaneously, detection efficiency ishigh in every reaction t
