Abstract
A centrifuge vessel (10) for performing automated immunoassays is disclosed. The centrifuge vessel (10) comprises a center tube (11) and an outer waste chamber (15). A biomaterial (18) is held within the center tube (11) and is capable of binding specific analytes in test samples. In operation, the centrifuge vessel (10) is rotated at high speed about its longitudinal axis, thereby causing all fluid within the center tube (11) to be transported into the outer waste chamber (15) while the analyte of interest remains bound to the biomaterial (18) positioned within the center tube (11).
